Memory-boosting tips

Dr. Fabiny suggests the following tips and tricks:

• Follow routines, such as leaving your car keys, glasses, and cell phone in the same place every day so that finding them becomes a “no brainer.”
• Slow down and pay attention to what you are doing to give your brain’s memory systems enough time to create an enduring memory.
• Avoid distracting or noisy environments and multitasking — the major memory busters in today’s fast-paced society.
• Get enough sleep, reduce stress, and check with your doctor to see if any of your medications affect memory — all potential memory spoilers.
