The symptoms of dementia can be treated to provide temporary improvement, but there is no treatment or cure for dementia caused by Alzheimer’s disease and other progressive dementias, according to the Alzheimer’s Association. Senile dementia is a misnomer that is derived from the erroneous belief that senility comes with age.
Treating the cause of the dementia is sometimes possible, according to WebMD. For example, if dementia is caused by a brain tumor, removing the tumor can alleviate dementia symptoms. If encephalitis is causing the dementia symptoms, medicines to treat the infection can help, and if hypothyroidism is the cause, taking the proper thyroid medicine can cause a reduction in symptoms of dementia. Some doctors also recommend taking vitamin B12 to treat dementia caused by vitamin deficiency.
The goal of treatments for Alzheimer’s related dementia is to lessen the symptoms experienced, including confusion and memory loss, notes the Alzheimer’s Association. Two types of drugs are available for treatment of cognitive symptoms that tend to accompany Alzheimer’s disease, as of 2015. These two types of drugs include memantine, which is sold under the brand name Namenda, and cholinesterase inhibitors, which are sold under the brand names Cognex, Exelon, Razadyne and Aricept. These medications can help to stabilize Alzheimer’s patients for a limited amount of time.
