Full Answer

Cognitive and neuropsychological tests can determine if a patient has dementia, what part of the brain is affected and how severe it is. These tests evaluate cognitive functions such as reasoning, memory and attention, states Mayo Clinic.

Brain scans can rule out health complications such as tumor or stroke that can cause symptoms of dementia. Laboratory tests can identify underlying physical problems such as low thyroid or vitamin B-12 deficiency, whereas neurological evaluations help diagnose other health conditions causing symptoms. Psychiatric evaluation can determine if symptoms result from a psychological condition such as depression, reports Mayo Clinic.
