Alzheimer's disease is an incurable brain disorder that causes progressive memory loss, personality changes and reduction in basic living skills. Patients eventually lose control over most mental and physical functioning and need continuous care. Symptoms typically begin after age 60 and the disease is most common after age 80. Certain dietary supplements may help prevent, delay or reduce symptoms, although more research is necessary, as noted by the University of Maryland Medical Center (UMMC). Some supplements can cause serious side effects if combined with medications for Alzheimer's or other health conditions.
Omega-3 Fatty Acids
Omega-3 fatty acids, prevalent in oily fish and fish oil supplements, are associated with a reduced risk of heart attack and stroke. Research has also linked high intake of these fatty acids to a possible decrease in risk of cognitive decline or dementia, according to the Alzheimer's Association. The effect may be due to positive effects on the cardiovascular system, anti-inflammatory effects, and protection of nerve cell membranes. In laboratory cell cultures, omega-3 fatty acids stimulated growth of branches connecting cells to each other. Dense branches are important for the brain's ability to process, store and retrieve information.
Huperzine A
A moss extract known as huperzine A has properties similar to cholinesterase inhibitors, a type of medication used for treating Alzheimer's. Some research indicates huperzine A may have comparable effectiveness to these drugs, according to the Alzheimer's Association. Patients should not take both cholinesterase inhibitor medications and huperzine A because the combination can increase side effects.
Lemon Balm
Research indicates lemon balm may help improve cognitive function and reduce agitation in Alzheimer's patients, according to the UMMC. This herb was used as far back as the Middle Ages to reduce stress and anxiety and to improve sleep.
Vitamins
Low levels of vitamin A and beta-carotene have been linked to Alzheimer's disease, as noted by the UMMC. Research also indicates that vitamin A can improve neurological functions like learning and memory. Additionally, a study published in a 2001 issue of "Neurology" found that participants with low levels of vitamin B9 (folate), vitamin B12 (cobalamin), or both, had significantly higher risks of developing Alzheimer's disease. Another type of dementia is associated with lack of vitamin B1 (thiamine). Monitoring blood levels of these vitamins in elderly people may be beneficial for preventing Alzheimer's disease.
