TYPES OF DEMENTIA
Definition: Most common type of dementia. It accounts for an estimated 60 to 80 percent of cases. It is a slowly progressive brain disease that begins well before symptoms are evident.
Symptoms: Difficulty remembering recent conversations, names, or events are often early symptoms, as are apathy and depression. Later symptoms include impaired communication, poor judgment, disorientation, confusion, behavior changes and difficulty speaking, swallowing and walking.
Definition: Previously known as post-stroke dementia, vascular dementia is less common than Alzheimers, accounting for about ten percent of dementia cases.
Symptoms: Impaired judgment or ability to make decisions, plan, or organize are likely to be initial symptoms, as opposed to the memory loss often associated with the initial symptoms of Alzheimer’s. Vascular dementia occurs from blood vessel blockage or damage leading to strokes or bleeding in the brain.
DEMENTIA WITH LEWY BODIES (DLB):
Definition: Lewy bodies are abnormal clumps of protein that develop in a part of the brain called the cortex. The brain changes of dementia with Lewy bodies alone can cause dementia, or they can be present at the same time as brain changes caused by Alzheimer’s disease and/or vascular dementia. When this happens, the individual is said to have mixed dementia.
Symptoms: People with dementia with Lewy bodies often have the memory loss and reasoning problems common in Alzheimer’s and are likely to have symptoms earlier–such as sleep disturbances, visual hallucinations, slowness, gait imbalance, or other Parkinson-like movements.
Definition: In mixed dementia, abnormalities linked to more than one cause of dementia occur simultaneously in the brain.
Symptoms: Characterized by the hallmark abnormalities of more than one cause of dementia, with common dementia symptoms.
Definition: A progressive disease of the nervous system marked by tremor, muscular rigidity, and slow, imprecise movement–chiefly affecting middle-aged and elderly people
Symptoms: Problems with movement–slowness, rigidity, tremor and changes in gait–are common symptoms of the disease. As Parkinson’s disease progresses, it often results in a progressive dementia similar to dementia with Lewy bodies or Alzheimer’s.
FRONTOTEMPORAL LOBAR DEMENTIA:
Definition: Includes dementias such as behavioral-variant frontotemporal lobar degeneration (FTLD), primary progressive aphasia, Pick’s disease, cortico-basal degeneration, and progressive palsy.
Symptoms: Typical symptoms include changes in personality and behavior and difficulty with language. Nerve cells in the front and side regions of the brain are especially affected.
Definition: This is the most common human form of a group of rare and fatal brain disorders affecting people and certain other mammals. A specific form called variant Creutzfeldt-Jakob disease is believed to be caused by consumption of products from cattle affected by mad cow disease.
Symptoms: Rapidly fatal disorder that impairs memory and coordination and causes behavior changes.
Definition: Memory issues caused by the buildup of fluid in the brain. Can sometimes be corrected with surgery by inserting a shunt to drain excess fluid.
Symptoms: Symptoms include difficulty walking, memory loss, and inability to control urination.
Definition: Huntingtons disease is a progressive brain disorder caused by a single defective gene on chromosome 4.
Symptoms: Abnormal involuntary movements, a severe decline in thinking and reasoning skills, irritability, depression, and other mood changes.
Definition: Korsakoff syndrome is a chronic memory disorder caused by a severe deficiency of thiamine (vitamin B-1). The most common cause is alcohol addiction.
Symptoms: Memory problems may be strikingly severe while other thinking and social skills may be unaffected.
