Understanding Dementia​

The term "dementia" is an overall term for a loss of cognitive functioning - thinking, remembering and reasoning - that interferes with daily life.  While there are more than 80 known underlying diseases and conditions that cause dementia, the brain failure is most commonly organized by the root pathology.

 

The most common pathologies are: Alzheimer's disease, Lewy Bodies dementia, Frontotemporal dementia and mixed dementia.   Other types and causes encompass numerous other conditions including: neurodegenerative & genetic, vascular & infections, traumatic & toxic/metabolic, structural & rare.

 

Dementia is more than just memory loss; it is brain failure due to brain  changes, diseases and conditions characterized by a decline in memory, language, problem-solving and other thinking skills that affect a person's ability to perform activities of daily living. Some types of dementia are permanent and incurable.  Some types of brain failure can be temporary, such as brain failure due to a urinary tract infection (UTI) or "Aids Brain" (when a person stops taking his/her medications).
