Lewy body dementia (LBD) is a progressive neurological disorder that affects the brain and can cause a variety of cognitive, behavioral, and physical symptoms. It is estimated to affect an estimated 1.4 million Americans. The exact cause of LBD is unknown, however, it is believed to be related to the buildup of abnormal proteins called alpha-synuclein in the brain.
The age at which a person may begin to experience the symptoms of LBD is difficult to determine, as the disease can affect people differently. Generally, the age of onset is between 50 and 85 years old. However, there have been reports of people in their 40s and even 30s who have been diagnosed with the disease.
The early signs and symptoms of LBD often manifest in the form of cognitive impairment, such as changes in memory and executive functioning. Additionally, people with LBD may experience changes in movement, such as tremors, slowness or rigidity, as well as visual hallucinations, changes in behavior, and sleep disturbances.
In conclusion, while the exact age at which Lewy body dementia begins is difficult to determine, it generally affects people between the ages of 50 and 85. Early signs and symptoms of the disease often manifest in the form of cognitive changes, movement changes, and changes in behavior.
