What are the Causes of Memory Loss?

The human brain and the way in which it stores and retrieves information is a subject of debate and speculation. Modern science has its limits when it comes to understanding the functions of the brain and how it affects memory. There are many possible causes of memory loss; however, each case of memory loss can be caused by different factors and life experiences.

Some memory loss is normal, and a part of the aging process. As we age, we lose brain cells, and as this happens we can become forgetful. Aging of the brain begins when most people are in their twenties.

As humans age we tend to have problems recalling information from the short term, and even long term memory. This type of memory loss is common, and steps can be taken to help recall information. For example, being introduced to someone and then quickly forgetting the person's name is normal, as is not being able to recall a childhood friend's name from many years ago. Strategies to combat this might be to repeat information aloud as it is provided, or to try to recall other information from years ago which might cue the long term memory.

Other causes of memory loss are temporary and can be blamed on such things as stress, depression, emotional trauma, lack of sleep, head injury, migraine headaches, pregnancy, nutritional deficiencies, infection, stroke, drugs, alcoholism, and medication. Memory loss that is caused by such factors is often times sudden, and in most cases reversible. Nutritional deficiencies can be caused by a lack of vitamin B12, and this can be remedied by increasing B12 consumption through diet or as prescribed by a physician.

Any memory loss that causes disruptions or even danger in a person's daily activities is considered serious. Serious memory loss worsens over time, and can be caused by many different factors. Head injury, infections in the brain, tumors, stroke, amnesia, Parkinson's disease, and Alzheimer's disease are all common causes of serious memory loss, which is not always reversible, though much of the time treatable. Prolonged drug use and alcoholism can also lead to permanent or serious memory loss.

The causes of memory loss are very diverse. Although many of them can be remedied, others create a situation that people simply have to adjust to. If it seems that memory loss is causing disruptions or dangers to yourself or someone you know, a physician should be consulted as soon as possible. There are tests available to help determine the cause or causes of memory loss, and treatment or therapy can be provided in many situations.
