New medical treatments for dementia include the use of acetylcholinesterase inhibitors, memantine hydrochloride, antipsychotics and antidepressants, according to NHS Choices. Although dementia cannot be cured medically, medications can help prevent symptoms from becoming worse.
These drugs help improve memory loss and other signs of dementia, NHS Choices notes. The treatments are meant to maintain the disorder for some time. Psychological treatments are also used. Psychological treatments do not cure dementia, but they help patients to cope with the symptoms. The treatments include cognitive stimulation and reality orientation therapy, validation therapy and behavioral therapy.
In cases where dementia is caused by nutritional or hormonal deficiencies or conditions such as brain tumor or injury, cure may be possible if the underlying cause is successfully treated.
