Unfortunately most dementia related conditions cannot be cured. For most types of dementia, there is no way to slow or reverse cognitive impairment. There are medications and alternative treatments that are used to improve and alleviate symptoms. Treatments and medication will depend heavily on the specific dementia condition in question.
Current research suggests that exercise, diet, smoking, cardiovascular disease, cholesterol, diabetes, and mild cognitive impairment may all factor into the development of dementia. Making healthy lifestyle choices, especially during middle age, may be integral to dementia prevention.
Preventative measures include:
Reducing smoking, alcohol abuse, and recreational drug abuse
Participating in mentally stimulating, memory-training activities
Staying physically and socially active
Eating a healthy diet
Maintaining a regular exercise routine
Getting adequate, quality sleep
Adequately managing stress
Managing health problems such as high cholesterol, diabetes, and high blood pressure
