MEMORY LOSS /DEMENTIA

Memory loss (amnesia) is unusual forgetfulness. You may not be able to remember new events, recall one or more memories of the past, or both.

The memory loss may be for a short time and then resolve. Or, it may not go away, and, depending on the cause, it can get worse over time.

Causes of Memory Loss

• Medications (such as antidepressants, antihistamines, anti-anxiety medications, muscle relaxants, tranquilizers, sleeping pills, and pain medications given after surgery)
• Alcohol, tobacco, or drug use
• Smoking
• Sleep deprivation (Insomnia)
• Depression and stress
• Nutritional deficiency such as low vitamin B1 or B12
• Head injury
• Stroke

Memory loss may be a sign of dementia. Often, memory loss that disrupts your life is one of the first or more-recognizable signs of dementia. Other early signs might include:

• Asking the same questions repeatedly
• Forgetting common words when speaking
• Mixing words up — saying "bed" instead of "table," for example
• Taking longer to complete familiar tasks, such as following a recipe
• Misplacing items in inappropriate places, such as putting a wallet in a kitchen drawer
• Getting lost while walking or driving in a familiar area
• Having changes in mood or behavior for no apparent reason

Alzheimer's disease is most common cause of dementia  in elderly individuals older than 65
