Dementia is a group of diseases that cause a decline in cognitive function, memory loss, and other neurological problems. One lesser-known symptom of dementia is weight loss.

While memory loss is the most common symptom and the hallmark of dementia, in some cases, unexplained weight loss may be an early warning sign. Below we will look at how dementia causes weight loss and what it could mean if you or a loved one experience it as a symptom.

What is Dementia?

Dementia is a collection of symptoms that affect a person’s cognitive functioning. There are many different types of dementia, including Alzheimer’s disease, Huntington’s disease, and Parkinson’s disease.

Regardless of the type of dementia, the result is a gradual decline in cognitive function over time.

The symptoms of dementia can start slowly and gradually worsen over time. These symptoms can range from mild forgetfulness to a complete loss of memory, confusion, disorientation, and inability to perform even the most basic daily tasks.

The root cause of dementia remains unknown, but genetics, lifestyle factors, and environmental factors are some of the known contributors.
