There are two types of long-term memory: declarative or explicit memory and non-declarative or implicit memory. Explicit memory refers to information that can be consciously evoked. There are two types of declarative memory: episodic memory and semantic memory.

There are three main processes that characterize how memory works. These processes are encoding, storage, and retrieval (or recall).

Proven ways to protect memory include following a healthy diet, exercising regularly, not smoking, and keeping blood pressure, cholesterol, and blood sugar in check. Living a mentally active life is important, too. Just as muscles grow stronger with use, mental exercise helps keep mental skills and memory in tone.

Aerobic exercise, like running and swimming, appears to be best for brain health. That’s because it increases a person’s heart rate, “which means the body pumps more blood to the brain,” says Okonkwo. But strength training, like weight lifting, may also bring benefits to the brain by increasing heart rate.
