What is Dementia?
Dementia is a syndrome, a group of symptoms that occur together and characterize a condition. Dementia symptoms vary depending on the cause, but common signs and symptoms include the cognitive and psychological changes listed below.

Cognitive changes:
Memory loss
Difficulties communicating or finding words
Disorientation
Difficulty reasoning or problem solving
Difficulty handling complex tasks
Problems with planning and organizing
Difficulties with concentrating and focusing
Difficulty learning new things
Impaired movement
Confusion

Psychological changes:
Personality changes
Depression
Anxiety
Impaired judgement
Agitation
Hallucinations

Diseases that can cause Dementia:
Alzheimer’s Disease
Vascular Dementia
Lewy Body Dementia
Mixed Dementia
Parkinson’s Disease
Fronto-temporal Dementia
Creutzfeld-Jakob Disease
Normal Pressure Hydrocephalus
Huntington’s Disease
Wernicke-Korsakoff Syndrome

Value of SPECT
The value of SPECT in evaluating dementia is the ability to locate the specific areas of the brain that are affected as well as asses the severity. Based on the location of the abnormalities a possible cause of the dementia can be established. Although there is no direct cure, this information is valuable in developing a treatment plan that may delay the progression of disease and improve the quality of life. Because SPECT is a functional imaging modality, it can detect changes in the brain long before they can be observed in anatomical imaging (CT/MR).
