Drugs to Treat Dementia

Dementia is a condition characterized by diminished brain functions, according to the U.S. National Library of Medicine and the National Institutes of Health. It is often caused by brain disorders, such as Alzheimer's disease and Parkinson's disease. The condition is not curable, but there a number of prescription medications that are used for dementia patients.

Cholinesterase Inhibitors

• Cholinesterase inhibitors, such as Aricept, Exelon, Reminyl and Cognex, are used to increase levels of chemical messengers in the brain that are responsible for memory and judgment, according to the Mayo Clinic. They slow down the breakdown of chemical messengers, such as acetylcholine, according to MedicineNet. These drugs have traditionally been used to treat symptoms of Alzheimer's disease.

Namenda

• Namenda is a drug that has traditionally been used to treat symptoms of Alzheimer's disease. The drug helps increase levels of a chemical messenger in the brain called glutamate, which helps with memory and learning, according to the Mayo Clinic.

Anticonvulsants, Sedatives and Antidepressants

• According to MedicineNet, some doctors prescribe anticonvulsants, sedatives or antidepressants to relieve symptoms of dementia, such as seizures, depression and sleep disorders.

Hypnotics and Anti-Anxiety Drugs

• Some people with dementia have backwards sleeping patterns, such as sleeping during the day and staying up at night, according to Alzheimer Scotland. Hypnotics, such as Zimovane and Heminevrin, and anti-anxiety drugs, such as diazepam and lorazpam, can help relieve anxiety and/or help people to develop regular sleeping patterns.

Anti-Psychotic Drugs
