Dementia

Dementia is a general term used to describe a decline in mental ability severe enough to interfere with daily life. It is not a specific disease but rather a group of symptoms associated with a decline in memory, reasoning, and other cognitive skills. Alzheimer's disease is the most common cause of dementia, accounting for 60-80% of cases. A condition called Mild Cognitive Impairment can sometimes be a precursor to dementia. Symptoms of dementia can vary but often include memory loss, difficulty communicating, and impaired problem-solving abilities. As the condition progresses, individuals may also experience changes in mood, behavior, and personality. Currently, there is no cure for most types of dementia, but early diagnosis and appropriate care and support can improve the quality of life for those affected.

Dementia can be caused by various factors, and scientists have found that both genetic and environmental factors play a role. Dementia happens most often as the result of a neurodegenerative disease such as Alzheimer's, Parkinson's, vascular dementia, Lewy body dementia, and frontotemporal disorders. These conditions are characterized by the progressive degeneration of brain cells, leading to a decline in cognitive function, communication, and memory. While age is a significant risk factor, it's important to note that not all elderly individuals develop dementia, and genetics, lifestyle factors, and overall health play significant roles in the onset of the condition. See brain health section for more information on how to reduce your own risk for dementia.

Dementia can cause many changes in communication, and these changes will shift over the course of the disease. One of the most common complaints that people have is difficulty finding the words they want to say, or losing their "train of thought". It's important to know that subtle changes like this are also part of normal aging! It's when the difficulty interrupts the ability to participate in daily life, that individuals should seek advice from their doctors. See this link for additional information on normal age-related changes in communication and thinking. Additional challenges in communication can include difficulty understanding and processing spoken or written information, leading to frustration on the part of the persons with dementia and their care partner or family members. Individuals may also have difficulty in social situations, showing less inhibition or less ability to process nonverbal communication like body language and facial expressions.

Memory loss is one of the hallmark symptoms of dementia, affecting short-term and long-term memory. Individuals may struggle to recall recent events, conversations, or names, as well as process new information. This can lead to disorientation and confusion, impacting their ability to perform daily tasks. Cognitive functions such as reasoning, judgment, and problem-solving can also be affected, leading to safety concerns in the home and community.
