About Lewy body Dementia

• It is a complex and challenging brain disorder.
• It is the second most common type of dementia after Alzheimer's disease. 
• LBD is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. 
  • These deposits, called Lewy bodies, affect chemicals in the brain. 
  • These changes, in turn, can lead to problems with thinking, movement, behavior, mood, and other body functions.
• There are two forms of LBD that cause cognitive symptoms — dementia with Lewy bodies and Parkinson's disease dementia.
• LBD  causes a decline in mental abilities that gradually gets worse over time. 
• LBD typically begins at age 50 or older, although sometimes younger people may have it. 
• LBD appears to affect slightly more men than women.
• The disease lasts an average of five to seven years from the time of diagnosis to death, but it can range from two to 20 years.
• People with LBD might see things that aren't there, known as visual hallucinations. 
• They also may have changes in alertness and attention.
• People with LBD commonly have symptoms of Parkinson's disease.  These symptoms might include rigid muscles, slow movement, trouble walking and tremors.
• As the disease worsens, people with LBD require more and more help with daily activities due to a decline in thinking and movement abilities. 
• In the later stages of the disease, people may depend entirely on others for assistance and care.
• Treatment: 
  • There’s no cure for Lewy body dementia and no way to prevent it. 
  • But medications and therapies can help manage symptoms for a while.
