Dementia in Parkinson disease – This condition occurs in individuals with Parkinson’s disease, characterized by a decline in cognitive abilities such as memory, attention, and problem-solving. It typically progresses gradually, with symptoms worsening over time. Patients may experience difficulties with daily activities and changes in mood or behavior.
Dementia in Alzheimer disease, atypical or mixed type – This form of dementia involves symptoms that do not fit the typical pattern of Alzheimer’s disease, often including a mix of cognitive impairments. It progresses with a decline in memory, language, and other cognitive functions, affecting the ability to perform everyday tasks.
Vascular dementia, unspecified – This type of dementia is caused by problems in the blood supply to the brain, leading to cognitive decline. The progression can vary, with symptoms such as confusion, disorientation, and difficulty with concentration and communication.
Multi-infarct dementia – This condition results from multiple small strokes that cause damage to brain tissue, leading to a decline in cognitive abilities. It progresses in a stepwise manner, with sudden changes in symptoms following each stroke.
Dementia in other specified diseases classified elsewhere – This category includes dementia associated with various other medical conditions. The progression and symptoms depend on the underlying disease but generally involve a decline in cognitive functions.
Dementia in Alzheimer disease with late onset – This form of Alzheimer’s disease begins after the age of 65 and is characterized by a gradual decline in memory and cognitive abilities. It progresses slowly, affecting daily living activities and social interactions.
Dementia in Alzheimer disease, unspecified – This type of dementia involves a decline in cognitive functions without specific distinguishing features. It progresses with memory loss, confusion, and difficulties in communication and reasoning.
Mixed cortical and subcortical vascular dementia – This condition involves damage to both the cortex and subcortex areas of the brain due to vascular issues. It progresses with symptoms such as memory loss, confusion, and difficulties with movement and coordination.
Dementia in human immunodeficiency virus [HIV] disease – This form of dementia occurs in individuals with HIV, leading to cognitive decline due to the virus’s impact on the brain. It progresses with symptoms like forgetfulness, confusion, and difficulty concentrating.
Dementia in Alzheimer disease with early onset – This type of Alzheimer’s disease begins before the age of 65, characterized by a rapid decline in cognitive abilities. It progresses with memory loss, language difficulties, and impaired judgment.
Subcortical vascular dementia – This condition is caused by small vessel disease affecting the subcortical regions of the brain, leading to cognitive decline. It progresses with symptoms such as slowed thinking, difficulty with attention, and changes in mood.
Dementia in Pick disease – This rare form of dementia is characterized by progressive damage to the frontal and temporal lobes of the brain. It progresses with changes in personality, behavior, and language abilities.
Dementia in Huntington disease – This condition occurs in individuals with Huntington’s disease, characterized by a decline in cognitive functions and motor skills. It progresses with symptoms such as memory loss, impaired judgment, and difficulty with movement.
Vascular dementia of acute onset – This type of dementia occurs suddenly following a major stroke or series of strokes. It progresses with symptoms like confusion, disorientation, and difficulties with speech and movement.
Unspecified dementia – This category includes dementia cases where the specific cause is not identified. It progresses with a general decline in cognitive abilities, affecting memory, communication, and daily activities.
Dementia in Creutzfeldt-Jakob disease – This rare and rapidly progressing form of dementia is caused by prion disease, leading to severe cognitive decline. It progresses with symptoms such as memory loss, personality changes, and impaired coordination.
Other vascular dementia – This category includes various forms of dementia caused by vascular issues not specified elsewhere. It progresses with cognitive decline, affecting memory, reasoning, and the ability to perform daily tasks.
