Alzheimer's disease is a neurodegenerative disorder that is the most common form of age-related dementia. Alzheimer's is caused by the formation of protein plaques in the brain that disrupt neuronal communication. Those who suffer from Alzheimer's have difficulty in memory recollection, disruption in simple motor skills, and further cognitive decline. There is no cure for Alzheimer's disease, but the symptoms can be managed with lifestyle modifications and medications.
Cholinesterase Inhibitors
There are two types of drugs that have been approved by the FDA for the treatment of Alzheimer's disease: cholinesterase inhibitors and memantine. Cholinesterase inhibitors are used to improve neuronal communication by inhibiting the degradation of a nerve signaling molecule called acetylcholine. The three brands of prescribed cholinesterase inhibitors include Aricept, Exelon and Razadyne. Minor side effects associated with cholinesterase inhibitors include gastrointestinal ailments like nausea, vomiting and diarrhea.
Memantine
Memantine, also known as Namenda, is approved for treatment of moderate to severe Alzheimer's disease. According to the Alzheimer's Association, memantine may improve cognitive function by improving memory, reason, language and attention. Memantine works on a different neuronal communication molecule called glutamate. Side effects of memantine use may include headache, confusion, dizziness and constipation.
Omega-3 Fatty Acids
There is minimal evidence that foods that are rich in omega-3 fatty acids may help prevent the onset of Alzheimer's disease. Fatty fish like mackerel, herring, salmon, tuna and sardines are great food sources of omega-3 fatty acids. According to an epidemiological survey reported by Rush University Medical Center, people who ate fish at least once per week lowered their risk of developing Alzheimer's disease by 60 percent.
