Benefits of Demezil Tablet

In Alzheimer's disease

In people with Alzheimer’s disease, certain nerve cells die in the brain. This results in lower levels of a chemical called acetylcholine which helps nerve cells to communicate with each other. This leads to symptoms of dementia such as memory loss, confusion, disorientation, problems with speech and language, and personality changes. Demezil 5mg Tablet increases the amount of acetylcholine and helps brain cells to communicate. It can, therefore, improve some of the symptoms such as memory, awareness, and the ability to carry out daily functions for a time. However, it is not a cure. You should use the medicine exactly as prescribed. It can take several weeks for your symptoms to improve; so keep using the medicine even if you do not think it is working.
