Lewy body dementia (LBD) is a progressive brain disorder that impairs thinking, movement, memory, and behavior. It is the second most common type of dementia after Alzheimer’s, affecting up to 1.4 million Americans. LBD is a particularly challenging form of dementia, and it can be difficult to diagnose and manage.
Symptoms of Lewy Body Dementia
The most common symptom of LBD is cognitive impairment, which can include difficulty concentrating or remembering recent events. Other symptoms can include:
• Visual hallucinations
• Changes in alertness or attention
• Tremors or other motor disturbances
• Problems with speech and language
• Disorientation and confusion
• Agitation or aggression
• Anxiety or depression
Causes of Lewy Body Dementia
LBD is caused by the presence of abnormal protein deposits, or Lewy bodies, in the brain. These deposits disrupt the normal functioning of the brain and can lead to the development of dementia. The exact cause of Lewy bodies is unknown, though genetics and environmental factors are thought to play a role.
Diagnosis of Lewy Body Dementia
LBD is often difficult to diagnose because it can resemble other types of dementia, such as Alzheimer’s. A diagnosis of LBD can only be made through a comprehensive assessment that includes a physical exam, lab tests, and cognitive testing.
Treatment of Lewy Body Dementia
There is no cure for LBD, but there are treatments available to help manage symptoms. These may include medications, lifestyle changes, and cognitive and occupational therapy. In severe cases, hospitalization may be necessary.
Prognosis of Lewy Body Dementia
LBD is a progressive disorder, meaning it will get worse over time. The severity of the symptoms and the progression of the disease can vary from person to person. The average life expectancy for someone with LBD is three to nine years after diagnosis.
