Here's a nice tricky question i came across, which could help clear it up...either way....

 

 

 

A 64 year old patient presents with progressive memory loss, gait disturbance, and urinary incontinence. He has a history of head injury of moderate severity in the past. Which of the following regarding his diagnosis is correct?

Babinski's sign is usually present
Cortical type of dementia is most common
Elevated CSF pressure will be noted on lumbar puncture
Enlarged ventricles can be seen on neuroimaging
Seizure is a common complication

In classic NPH, a head CT shows a moderate to severe ventricular enlargement out of proportion to cerebral atrophy and includes ballooned frontal horns and enlarged temporal horns without evidence of hippocampal atrophy. Seizure is rare; Babinski is usually absent. Subcortical dementia is more common.

What about this from SPMM:

Dementias may be classified in terms of primary site of pathology

 Cortical dementias

 Fronto-temporal: Pick’s disease, Normal pressure hydrocephalus,

and Motor neuron disease- featured by gross personality changes

 Posterior-parietal: Alzheimer’s disease-featured by early memory

loss and focal cognitive deficits

 Sub cortical dementias: Parkinson’s disease dementia, Huntington’s

disease, HIV associated dementia, Binswanger’s disease and Wilson’s

disease-characterised by gross psychomotor slowing, abnormal

movements, low mood, mild amnesia and apathetic personality.

 Cortical-sub cortical dementia: Lewy Body Dementia. Both cortical and sub

cortical symptoms are present

 Multifocal dementias: Creutzfeldt-Jakob disease. Involves cerebellum and

subcortical structures
