Alzheimers diease affecting the parietal lobe is associated with worse prognosis?

true

Ref Manchester notes

Reality orientation has lasting beneficial effects when used to treat people with alzheimers.

False

reference: Seminar series old age

retrograde amnesia is due to retrograde interference

FALSE

They are two distinct albeit related concepts.

Retroactive interference: Newly learned information hurts memory for old information.

or else:

retroactive inhibition/interference

'Forgetting caused by learning material after the to-be-remembered episode'(Benjamin, Hopkins, & Nation, 1994. p.279)

retrograde amnesia

A loss of memory for events occurring before the onset of amnesia. Specifically, the word retrograde means moving or tending (to go) backward. (Kurland and

The memory degredation curve starts off gradual and then becomes progressively steeper.

FALSE

The other way around: memory degradation should refer to the speed of information loss from STM to LTM. According to Psychol basis of Psych pag 164 this starts steeply and then slows down once it is fixed in LTM.

10% of alzheimers is due to variations in the preselinin gene i think FALSE. there are 2 presenelin genes implicated in the aetiology of alzheimers. both are less than 5%. ref:http://www.mtsinai.on.ca/FamMedGen/Disorders/alzheimers.htm#table1'>http://www.mtsinai.on.ca/FamMedGen/Disorders/alzheimers.htm#table1 <http://www.mtsinai.on.ca/FamMedGen/Disorders/alzheimers.htm> Early Onset- chromosome 14: Presenelin I (PS-1) <5%.

in Alzheimers disease there is decreased latency in the evoled responses(evoked potentials?) in EEG

False?

evoked potentials

7. presence of birth injury affects the age of onset of SCZ

True

Byrne et al. (2000) Compared obstetric records of 431 patient–control pairs. Linked with psychiatric case register. Global rate of OCs did not differ between patients and controls. Male patients with a young onset had significantly more OCs than controls.

Rosso et al. (2000) 1955 Finnish birth cohort. 80 patients, 61 unaffected siblings, and 56 matched controls. Hypoxia-associated OCs significantly increase the odds of early-onset schizophrenia (but not of later-onset schizophrenia).

RE: AUTISM and SCZ

Guys, Bleuler's autism has nothing to do with autism (PDD) as a diagnosis. (although the feature e.g isolative behaviours are common)

That autism is a predecessor of Schizophrenia was an early misconception by Kanner, the guy who described autism.

Note the conclusion of a study in the AJP. Granted, this is a 1991 study.

If the present study group is taken to be representative, it appears that the frequency of schizophrenia among autistic patients (0.6%) is roughly comparable to the frequency of schizophrenia in the general population.

RE: Incidence rates of Schizophrenia in Barbados vs. U.K.

The age-corrected incidence rate for schizophrenia per 10 000 is 2.09 in Jamaica, 2.2 per 1000 in Trinidad, and 2.92 in Barbados. These rates are lower than the incidence rates reported for white British people, and significantly lower that the 6- to 18-fold higher risk ratio incidence reported for African Caribbeans living in Britain.

MCPP is a 5-HT2a antagonist. true

mCPP antagonist with moderate affinity at the 5-HT2A and 5-HT3 receptors, a partial agonist with approximately a ten times lower affinity at the 5-HT1A, 5-HT1B, and 5-HT1D receptors, and a weak partial agonist at the 5-HT2B receptor with an affinity equal to that of the 5-HT2C receptor (Kennett et al.1994).

Duloxetine is a serotonine and NA reuptake inhibitor T

It weakly inhibits dopamine reuptake , with NO significant affinity for histaminergic, dopaminergic, cholinergic and adrenergic receptors. It is extensively metabolised by oxidative enzymes (CYP1A2 and CYP2D6). The half life of duloxetine ranges from 8 to 17 hrs (mean 12 hrs). (and NOT 24 hrs).

Ref: SPC, Cymbalta

4) Acamprosate is an NMDA antagonist TRUE

Neuropharmacology. 2001 May;40(6):749-60. Related Articles, Links

The anti-craving compound acamprosate acts as a weak NMDA-receptor antagonist, but modulates NMDA-receptor subunit expression similar to memantine and MK-801.

5) Carbamazepine is associated with hypothyroidism

TRUE

1/Long-term treatment of children with epilepsy with valproate or carbamazepine may cause subclinical hypothyroidism.

Eiris-Punal J, Del Rio-Garma M, Del Rio-Garma MC, Lojo-Rocamonde S, Novo-Rodriguez I, Castro-Gago M.

2/Our data suggest that children treated with carbamazepine may have subclinical signs of hypothyroidism, and these changes are more evident if carbamazepine is given in association with valproic acid, while no alteration in thyroid hormones can be found with valproic acid monotherapy. Thyroid-stimulating hormone and thyrotropin-releasing hormone levels do not seem to be affected by these drugs, suggesting that hypothalamic function is not affected in these children.

4.Duloxetine has a half life of 24 hours FALSE

Pharmacokinetics: The elimination half-life for duloxetine is approximately 12 hours, with a range of 8-17 hours.

http://www.clevelandclinicmeded.com/medical_info/pharmacy/septoct2004/du loxetine.htm

5.Mirtazapine blocks H1 receptors TRUE

Mirtazapine is a presynaptic alpha-2 antagonist that has dual action by increasing noradrenergic and serotonergic neurotransmission. The enhancement of serotonergic neurotransmission is specifically mediated via 5-HT1 receptors because mirtazapine is a postsynaptic serotonergic 5-HT2 and 5-HT3 antagonist. In addition, mirtazapine has only a weak affinity for 5-HT1 receptors and has very weak muscarinic anticholinergic and histamine (H1) antagonist properties. As a consequence of its unique pharmacodynamic properties, mirtazapine is an effective, safe and well-tolerated addition to the antidepressant armamentarium. Mirtazapine is well absorbed from the gastrointestinal tract following oral administration, and it is extensively metabolized in the liver to four metabolites via demethylation and hydroxylation, followed by glucuronide conjugation.

http://www.biopsychiatry.com/mirtazapine.html

6.Clozapine causes akathisia less than risperidone in any dosage. TRUE

The point-prevalence of akathisia was 7.3% in the clozapine group, 13% in the risperidone group, and 23.8% in the group treated with conventional antipsychotics.

Psychology:

When a mother remarries, daughters experience more distress than sons. - TRUE

According to goodman and Scott.

so it goes like this:

when parents divorce - boys more distressed

when mother remarries - girls more distressed

100% sure about this one

in psychodynamic psychotherapy interpretations should always be tentative.

F-always is almost always wrong

Group analysis is of the group,by the group ,for the group.F

Gestalt psychology includes law of closure

T-also proximity,similarity,simplicity,continuity. malhi&mitchell1999-pgg5

10) women are more suggetible than men under interrogation

F-as earlier

Group analysis is of the group,by the group ,for the group.

A patient failing to attend a therapy group who have critisized her is what Bion referred to as the basic assumption.

Bion perceived three basic assumption groups: the dependency group, the fight-flight group, and the pairing group. Dependency groups operate on the assumption is that there is a leader (not necessarily the therapist) who can magically gratify the group's need for security and nurture. Another Basic Assumption is that the group must protect itself. It does this by either fighting or running away from something threatening. Naturally enough, Bion called this the 'fight-flight' group. Since it is not unusual (especially in a therapy group) for the Work-Group tasks themselves to feel threatening, it is not uncommon for the nominal leader to be avoided or fought against.

so its not attending the group,

82) If you disagree with the attitude of someone you like you will change your attitude rather than change your opinion of the person

True

Congruity theory me thinks

8. Gender differences exist in the moral development of children

True

More recent approaches to explain moral development are the gender-based theories. Carol Gilligan asserts that male and female morality develop along different tracks. Women's moral development ends in compassion and an ethics of caring, whereas men's morality culminates in a moral system that is dominated by the ethics of justice and the assertion of rights

Kaplan & Sadock's

9.A patient failing to attend a therapy group who have critisized her is what Bion referred to as the basic assumption.

False

Basic assumptions, are dependency, fight or flight, and pairing.

In dependency, the group tries to elicit protection through passive or dependent behaviour. In fight or flight they will attack the therapist or some other issue, or retreat and withdraw. In pairing they may create a group illusion that some magical form of rescue may arise from the dilemmas of group life through charged partnerships.

9.Underlying assumptions are process that belong to the dynamic unconsciousness

True

personal dynamic unconscious reflects developmental vicissitudes and residues of a life history.

1.Habituation can exacerbate panic avoidance.

False

Repeated presentation of the same stimulus can have two consequences: sensitization or habituation. The former involves an increase in responding, and the latter involves a decrease. Slow rates of stimulus presentation are relatively more likely to result in sensitization, and rapid rates are more likely to result in habituation.

6.projective identification is a defence mechanism against unconsious anxiety

True

One member of a couple has an affair, the other, unable to show directly their hurt, may retaliate by themselves sleeping with someone else. Here the initially injured party communicates pain, humiliation, and rage not by direct expression of anger, but by inducing those feelings in the other via PI

2.Negative reinforcement can exacerbate the avoidance in phobic avoidance.

TRUE - Negative reinforcement means that an aversive stimulus is present before a behaviour, so that once the desired behaviour occurs the adversive stimulus stops thus increasing the probability of that desired behaviour reoccurring. This learned response is called avoidance conditioning

Punishment is where an adversive stimulus is appiled after a given behaviour (usually an undesired one) occurs

- Revision notes in Psychiatry

8.Transference phenomena does not effect the therapist

False - it is the reactions that the patient projects pnto the therapist... must affect the therapist in some way (my own interpretation)

4.Rational emotional therapy is of proven benefit for patients with emotionally unstable personality disorder

True

The XYY syndrome is present in 1 in 800 boys. Males with XYY syndrome tend to be tall and to have nodulocystic acne at puberty. XYY males as a group, like XXY males(Klinefelter syndrome), reportedly are somewhat less intelligent than XY males. This may increase their risk of socialization and academic problems

Alcohol:

5. In treating dependence, the action stage follows contemplation

FALSE

Follows ready for action

(Pg 351, Comp to Psych St, 6th Ed, Johnstone et al)

The stage of change that a person can be identified as being at determines the therapeutic approach and type of treatment offered. Thus at the precontemplation stage where there is no recognition of a need for treatment, there is no point in offering intensive treatment interventions. Similarly, at the contemplation stage when treatment is being considered, the appropriate intervention is to help the person clarify their views and build their motivation to change rather than offering active treatment. Indeed, it is only in the decision and action stages that treatment should be actively offered and facilitated.

An individual who drinks in binges will experience different problems compared with someone who drinks the same amount of alcohol spread over a week or a month or a year. The way in which a person behaves while intoxicated is another important factor determining the nature of alcohol related problems. The social consequences of drinking such as job loss, imprisonment, marital and family break-up, and binge drinking have profound effects on the well being of the drinker, their families and society.

FALSE

Fragile X involves an expansion of the CGG repeats normally in the FMR1 (fragile X mental retardation 1) gene. The CGG repeats are not in a section of the gene that gets edited out (an intron), but rather in a section that is copied and remains after the editing is finished (an exon). Even though the repeat section is part of the finished messenger RNA (mRNA), it doesn't actually get translated into protein.

FALSE

Kendell and Zeally put it at 1 in 10000. It is generally accepted to be between 1 in 10000 and 1 in 12000 live births.

Phenylketonuria Prevalence and causes Phenylketonuria is caused by an inborn error of amino acid metabolism which affects approximately 1 in 12 000 people. This condition is inherited in an autosomal recessive manner and often causes severe mental retardation if it remains untreated. Affected subjects have fair hair, fair skin, and blue eyes because of the lack of the skin pigment precursor tyrosine. This metabolic disorder is caused by a deficiency of the hepatic enzyme, phenylalanine hydroxylase, which causes hyperphenylalaninaemia and phenylketonuria.

puri pg 461

(CCK) is a peptide neurotransmitter originally isolated from the gut but abundantly distributed in the CNS. In addition to its presence in pancreas and the gastrointestinal (GI) tract, CCK has been identified in mammalian brain, with high concentrations found in the cerebral cortex, limbic system, and hypothalamus. In animal studies, CCK is involved in the regulation of such behavioral functions as inhibition of intake of solid and liquid food, production of satiety, and pain relief. Of the two identified receptor subtypes, CCK type A (CCK-A) is found primarily in the periphery and in some discrete brain areas, whereas CCK type B (CCK-B) is plentiful in the brain.

2. PEPTIC ULCER IS A RECOGNISED COMPLICATION OF BULIMIA NERVOSA.... TRUE

Medical Complications:

Like all eating disorders bulimics are also at a high risk for dying, especially if they are purging, using laxatives and doing

excessive exercise. Many bulimics have died from cardiac arrest, which is usually caused by low potassium or an electrolyte imbalance. There have also been cases when bulimics have died because of a ruptured oesophagus due to excessive vomiting. Other complications that arise are:

Erosion of tooth enamel because of repeated exposure to acidic gastric contents

Dental cavities, sensitivity to hot or cold food

Swelling and soreness in the salivary glands (from repeated vomiting)

Stomach Ulcers

Ruptures of the stomach and oesophagus

Abnormal build-up of fluid in the intestines

Disruption in the normal bowel release function

Electrolyte imbalance

Dehydration

A greater risk for suicidal behaviour

Decrease in libido

Cathartic colon (caused from laxative abuse)

Edema (swelling of hands and feet)

Low blood pressure

Development of peptic ulcers and pancreatitis (inflammation of the pancreas)

Gastric dilation and rupture

Abrasions on back of hands and knuckles

Anaemia

Cardiac arrest and death

Treatment:

The treatment of bulimia consists of individual psychotherapy and nutritional direction. However, what you have to realise is that you cannot cure a bulimic by trying to control their behaviour or worse shrugging it off. What the patient needs is support. As most of the patients are very hard on themselves and they need support to help understand things better.

1. There is decreased short wave sleep in the elderly.

TRUE

KS CTP VII Ch 1.19

The amount of time spent in delta sleep (stages 3 and 4) each night peaks in early adolescence and gradually falls with age until it nearly disappears at about the age of 60. Young adults typically spend about 15 to 20 percent of total sleep time in delta sleep. By the age of 60 or 70, few individuals have any delta-wave activity during sleep. Interestingly, men tend to lose delta sleep at an earlier age than women. The loss of delta sleep results more from a reduction in amplitude than from fewer slow (0.5–2 Hz) waves. Some researchers have speculated that this might indicate accelerated aging in men.

. True - normal ageing brings about characteristic changes in sleep architecture, with increased sleep latency, reduced total sleep time, loss of SWS, frequent arousals leading to fragmentation of nocturnal sleep, and an increase in daytime napping.

Companion to Psychiatric Studies (p.788)

2. Old age and Alzheimer’s disease both show neuronal degeneration in layer 2 of the entorhinal cortex.

TRUE

KS CTP Ch 51.2

NORMAL AGING, NEURODEGENERATION, AND ALZHEIMER'S DISEASE

The most difficult problem in characterizing the normal aging of the human CNS is identifying a meaningful boundary between normal aging and abnormal neurodegeneration.

Plaques and Tangles

Senile plaques and neurofibrillary tangles are associated with Alzheimer's disease, Down syndrome, and other neurodegenerative diseases. Tangles are fibrous bands of intracytoplasmic inclusions consisting of paired helical filaments that seem to result from abnormal hyperphosphorylation and perhaps glycosylation of the microtubule-associated protein tau. Plaques consist of an b-amyloid core surrounded by microglial processes, dendritic processes, and sometimes neurites that may also contain paired helical filaments. While they are often called 'lesions,' implying pathology, both plaques and tangles occur in the brains of normal aged persons. Plaques may be found, in lower average numbers than in Alzheimer's disease, throughout the neocortex and in the hippocampus. Tangles accumulate with age first in layer II of the entorhinal cortex, later in the hippocampus and nearby temporal lobe areas, and later still in neocortex. There is a rough correlation between plaque counts (especially the neuritic type) and cognitive loss, but there is so much overlap between the counts in elderly adults without cognitive loss and in Alzheimer's patients that conventional neuropathological criteria for Alzheimer's disease require age-adjusted plaque counts. There is a better correlation between tangle counts and cognitive loss.

. False - in a small study comparing ERC in patients with Alzheimer's disease to elderly controls it was found that ERC had 40% volume loss in Alzheimer's disease. Volume of ERC was not dependent on age but degree of volume loss did correlate with disease severity.

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed &list_uids=12420152&dopt=Abstract

DHEA is a cholesterol-derived hormone secreted by the adrenal glands under control of ACTH. It is the most abundant steroid hormone in the body, circulating primarily in the sulfated form, DHEAS. Blood levels of DHEA and DHEAS are somewhat lower in women, but levels decrease significantly with age in both sexes. DHEAS has a long half-life (20 hours) and serves as a buffer from which DHEA, androgens and estrogens can be derived. DHEA competes with cortisol at the receptor level. For example, DHEA exerted a clear anticortisol effect when administered to immobilization-stressed rats.

“More recently, tonsil biopsy has been used for the presumptive identification of vCJD. Immunohistochemical testing for the prion protein in these tissues has demonstrated that the protein is present in patients with vCJD but not in patients with sCJD (Hill et al., 1999; WHO, 2001a). The postulated reasons for this difference include a strain effect, a species-barrier effect, or the oral route of exposure in vCJD (Hill et al., 1999). There have been too few case series to determine the sensitivity or specificity of this ancillary test.”

8. In delirium, onset of rigidity and cogwheeling is due to nicotinic acid deficiency

In delirium, onset of rigidity and cogwheeling is due to nicotinic acid deficiency -so possibly true

nicotinic acid deficiency- (merck manual)

CNS symptoms include (1) organic psychosis, characterized by memory impairment, disorientation, confusion, and confabulation (excitement, depression, mania, and delirium predominate in some patients; in others, the reaction is paranoid); and (2) encephalopathic syndrome, characterized by clouding of consciousness, cogwheel rigidity of the extremities, and uncontrollable sucking and grasping reflexes. Differentiating these CNS changes from those in thiamine deficiency is difficult.

10. Delirium may be caused by Wilson’s disease

TRUE

The most common presentations, in descending order, are neurological, hepatic, psychiatric, orthopedic, ophthalmological, hemolytic anemia, and cardiac. Neurological presentations are protean, but typically begin with basal ganglia signs of tremor or rigidity. The classic 'wingbeating' tremor is localized to the arms, usually absent at rest, and is elicited by extension. Parkinsonian or intention tremors may also be seen. Parkinsonian rigidity, dystonic postures, and occasionally choreo-athetotic movements are seen. Dystonia and rigidity of laryngeal, pharyngeal, and facial musculature may result in dysarthria, dysphagia, hoarseness, drooling, and the classic vacuous or fixed open-mouthed smile. The tendency for motor disorders to predominate in the bulbar musculature contrasts with parkinsonism. Loss of coordination, convulsions, coma, and delirium may occur. ...

4 Patients with Parkinson's disease are impaired in set-shifting tasks. Q 4 True re Impaired set shifting in parkinsons read from the web Tests which assess the ability to shift cognitive set modelled after the Wisconsin Card Sorting Test are particularly sensitive to impairments in patients with Parkinson's disease as well as in patients with frontal lobe damage. However, the underlying mechanisms responsible for the similar deficits observed in the two patient groups are not well understood and may not be identical. For example, an apparent deficit in set-shifting ability may reflect either an impairment in the ability to shift from a perceptual dimension which has previously commanded attention (i.e. 'perseveration'), or in the ability to shift to an alternative perceptual dimension which has previously been irrelevant (i.e. 'learned irrelevance'). In this study, the performance of both medicated and non-medicated patients with Parkinson's disease were compared with a group of neurosurgical patients with localized excisions of the frontal lobes on a novel task designed to assess the relative contribution of 'perseveration' and 'learned irrelevance' to impaired set-shifting ability. Patients with frontal lobe damage were worse than controls in their ability to shift attention from a previously relevant stimulus dimension. Medicated patients with Parkinson's disease were worse at shifting to a previously irrelevant dimension. In contrast to both groups, nonmedicated patients with Parkinson's disease were impaired in both conditions. These results suggest that the gross set-shifting deficits reported in both frontal lobe patients and patients with Parkinson's disease may involve fundamentally different, though related, cognitive processes, and that these may be differentially affected by medication. Specifically, L-dopa therapy may protect Parkinson's disease patients from preservation of attention to a formerly relevant stimulus dimension. PMID: 8221053 [PubMed - indexed for MEDLINE]

This refers to Neuroticism (N) as described by Eysenck. Extroversion/Introversion thought to be detemined by 'balance' of ascending reticular activating system (ARAS).

?TRUE

“Intravert is highly aroused - any stimulation is over stimulation

Extravert is low on arousal - stimulus hunger - low threshold for boredom”

http://www.a2zpsychology.com/a2z%20guide/mpi.htm

“Eysenck (1957, 1967) argued that levels of cortical activity contribute to the level of a person’s extroversion. His idea was that people have different levels of need for external activity based on their levels of internal activity.

Extroverts have little internal arousal and thus seek external stimulation.

Introverts generally have sufficient internal arousal and thus avoid external activity that would yield too much arousal.

Extending Eysenck’s argument, Gray (1973, 197)described extroverts as having emotional deficits resulting from low levels of arousal, which causes them to seek interaction with others to stimulate cortical arousal.”

The DST in children and adolescents with major depressive disorder

CD Casat, GW Arana and K Powell

Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston 29425.

The authors analyzed dexamethasone suppression test (DST) results from 13 prospective studies on the use of the DST in children and adolescents with psychiatric disorders. Sensitivity of the DST was significantly higher among the children than among the adolescents with major depressive disorder (69.6% and 47.1%, respectively), and specificity was significantly lower (69.7% and 80.2%). Significantly more adolescents with major depressive disorder than with other psychiatric diagnoses, especially conduct disorder, were nonsuppressors. The authors discuss possible explanations for the high DST sensitivity among the children and point out the potential usefulness of the DST in

differentiating major depressive disorder from conduct disorder.

12. Pantothenic acid deficiency cause dementia/delirium

13. Vitamin B12 deficiency commonly causes delirium

both false;

Pantothenic acid is widespread in foods, making deficiency very rare except for those with a highly processed diet since much of the vitamin B-5 activity is lost during the refinement process. Additionally, pantothenic acid is produced by beneficial bacterial in the digestive system. A reduction or destruction of intestinal flora, most commonly by antibiotic use, can contribute to vitamin B-5 deficiency.

There are claims that pantothenic acid can prevent graying and even restore hair to its natural color, but this is based on animal research that showed increased graying of the fur, decreased growth, progressing to hemorrhage and destruction of the adrenal glands.

In humans, pantothenic acid deficiency results in diminished adrenal gland function. A variety of metabolic problems will also manifest themselves. Fatigue is common along with depression, and problems associated with the digestive system. There will also be loss of nerve function and problems with blood sugar metabolism, with hypoglycemia being the most common.

Pantothenic acid deficiency can reduce immune system responses, increasing the risk of infection. Other symptoms of B-5 deficiency include skin problems, insomnia, lack of coordination, muscle cramps and worsening of allergy symptoms.

1. The plenum temporale is situated on the anterior part of inferior temporal lobe

False

Certain brain functions, such as language, are localized to one hemisphere . The structural bases for the lateralization of function have not been determined, but some anatomical differences between the cerebral hemispheres have been observed. For example, a portion of the superior temporal cortex, called the planum temporale (infolded cortex in the posterior portion of the sylvian fissure) , is generally larger in the left hemisphere than in the right hemisphere. That cortical area, which is located close to the primary auditory cortex and includes the region known as Wernicke's area appears to be involved in receptive language functions that are localized to the left hemisphere. In addition, Brodmann's area 44 in the left inferior frontal cortex contains larger pyramidal neurons than the homotopic region of the right hemisphere, a difference that may contribute to the specialization of Broca's area for motor speech function.
