Many people undergo the dementia-like symptoms as they are getting old. However, is it the true case of dementia? It's not easy to know. But the fact is, more than 50 conditions can mimic the symptoms of dementia.
The following are some common conditions that may be mistaken as dementia.
It can cause changes in mental functioning that closely resemble dementia, but there are two important differences:

Brain tumors can interfere with cognitive functioning and cause personality changes. Depending on their location, they can trigger other symptoms, such as headaches, seizures, or vomiting.

Consuming excessive alcohol for a long time can cause impaired thinking that resembles Alzheimer’s disease.
