Result of some other pathological process
- Secondary dementia
- (other pathological process is causing the disease)
What nursing interventions to determine pseudodementia
- Complete physical and history, exam incl. EEG, EKG, CT, CBC,B12, TSH.

Senile plaques: Degenative neuron materials. #'s of plaques-the more they have is related to the degree of dementia. the less memory they have.
Granulovascular degeneration: filling of brain cells w/fluid and degeneration of granulation.
The areas affected in the brain
Hippocampus: region to be first affected.

Clock drawing test
Detect depression can contribute or memic dementia.
