Causes of Lewy Body Dementia in Senior Adults in Sacramento, CA

Lewy body dementia is one of the most progressive types of dementia diagnosed in seniors. The development of Lewy bodies, which are abnormal deposits of a protein called alpha-synuclein in the brain, leads to nerve cell damage that results in problems with thinking, movement, behavior, and mood. Below are some details about Lewy body dementia, including causes of the condition and how to reduce the risk.


Lewy body dementia typically occurs in individuals over the age of 50, but some younger adults develop the condition for various reasons. The disorder is hereditary, so you should have your senior loved one tested for the gene, and make sure your loved one reviews his or her family history to determine if he or she is at higher risk. When an older adult experiences a buildup of Lewy bodies in the brain, the condition could develop. Tangles and plaques in the brain that are linked to Alzheimer’s could also cause Lewy body dementia.


Some seniors experience hallucinations and sleeping difficulties, while other individuals with Lewy body dementia have depression and poor cognition. If you notice your loved one moving more slowly, sweating, or experiencing significant digestive issues, he or she may have developed this disorder.

Other symptoms linked to Lewy body dementia include:

• Lack of motivation
• Dizziness
• Tremors
• Confusion
• Inability to focus
• Memory loss
• Visual-spatial problems

A highly trained caregiver with experience in caring for seniors with dementia can be a fantastic resource for family members. Families looking for top-rated home care service providers can reach out to Home Care Assistance. From respite care to specialized Alzheimer’s, dementia, stroke, and Parkinson’s care, there are many ways we can make life easier for seniors and their loved ones.


To diagnose Lewy body dementia, a physician will look at various factors, including your loved one’s ability to think. If there’s been a progressive decrease in critical thinking skills combined with frequent hallucinations or decreased alertness, the doctor will likely diagnose your loved one with Lewy body dementia. Some physicians look for other symptoms, including those associated with Parkinson’s disease. Although a medical professional focuses on traits and warning signs of other conditions to diagnose the disorder, you shouldn’t try this at home. The diagnosis should come from a trained, experienced physician.


There’s no cure for Lewy body dementia, but doctors can recommend prescriptions and therapy to treat many of the symptoms associated with the condition. For example, your loved one’s primary care physician may prescribe cholinesterase inhibitors, which increase the levels of the chemical messengers that boost memory and help with brain function. If your loved one displays traits associated with Parkinson’s, such as slow movement, the doctor may recommend carbidopa and levodopa medications to reduce muscle rigidity and other mobility problems. Some of the therapies that could treat Lewy body dementia include anger management techniques to address behavioral challenges and activities that boost cognitive function.
