Injury or changes in the brain cause dementia. Do you know that there are several causes of dementia? However, with treatment, some can be reversed, but most cannot be. Signs of dementia differ significantly between people and depend on the area and cause of the brain that is affected as well. There is no particular sign of dementia. There are several distinct signs, and a person who has dementia have many (but not all) of these signs. In several instances, the signs may go unrecognised and be subtle for some time, whereas other circumstances may have proclaimed signs. What is the first symptom of dementia? It is usually the memory loss. Essentially, the person has a lack of short-term memory, and next, all the features of consciousness are changed. The person may forget the name of an acquaintance or forget where kept an object just a few minutes ago.
What are the characteristic symptoms of dementia?
- Dementia causes the person to have highly detailed, frequent visual hallucinations. They may see other animals or people that are not real and may exhibit a trend to fall regularly.
- Fronto-temporal dementia: It may cause unusual behaviour or personality changes. People with such dementia might become less susceptible to other people’s passions—this makes them seem unfeeling and cold. They may say rude things or stop caring for others. They may expose themselves and often lose inhibitions or make sexually or derogatory unacceptable comments.
- Signs of dementia may begin quickly in vascular dementia, or it may occur slowly. They may also have stroke-like signs, such as paralysis or muscle weakness on the particular side of the body.
