Drug treatment is available to reverse some types of dementia, but not all, according to WebMD. Nevertheless, doctors may still prescribe the same drugs used to treat Alzheimer's disease to also improve mental conditions caused by dementia, states the Alzheimer's Association.
Common drugs used to treat memory loss from Alzheimer's disease are cholinesterase inhibitors and memantine, reports the Alzheimer's Association. These drugs address memory loss and confusion, as well as thinking and reasoning issues.
According to the Alzheimer's Association, dementia is a blanket term used to describe a range of conditions related to memory loss and declining mental function. The most common forms of dementia are Alzheimer's disease and vascular dementia, a form of dementia caused by stroke.
In cases where Alzheimer's disease is not the cause of dementia, treatment may improve or even reverse dementia, states WebMD. Such conditions include vitamin B-12 deficiency and hypothyroidism. Vitamin B-12 and thyroid hormones, respectively, can cure the condition and reverse dementia.
Other causes of dementia are depression, medications and alcohol, reports the Alzheimer's Association. Correct treatment of these conditions may improve dementia.
Symptoms of dementia include impaired memory, problems with communication and language, inability to focus, lack of reason and judgement and loss of visual perception, according to the Alzheimer's Association.
