Memory is the faculty of the brain by which data or information is encoded, stored and retrieved when needed. It is the retention of information over time in order to influence future action. The three main forms of memory storage are sensory memory, short-term memory and long-term memory. The human brain has an amazing ability to adapt and change, even in old age. This ability is known as neuroplasticity. You can harness the natural power of neuroplasticity to increase your cognitive abilities, improve your ability to learn new information, and improve your memory at any age. Whether you have Alzheimer's disease or just have memory problems, certain vitamins and fatty acids may slow or prevent memory loss. The long list of potential solutions includes vitamins like vitamin B-12, herbal supplements like ginkgo biloba and omega-3 fatty acids.
