Mild forms of memory loss are experienced by everyone, but incidence often increases with age. This type of memory loss does not usually adversely affect activities of daily living. However, a memory disorder which occurs as a result of illness may be significant enough to hamper your daily routine.
Memory disorders may be temporary or permanent, progress gradually as in Alzheimer's disease or begin suddenly as with brain trauma. You may retain older memories but may have trouble making new ones. Memory loss is usually caused by an underlying condition, which if treated, could reverse it.
Impairment in memory storage, retention, and recollection occurs as a result of mild or severe neurological damage to the brain that may be caused by neurodegenerative illnesses (Huntington's disease or Parkinson's disease), brain tumors, head injury, sleep deprivation, mental disorders (depression or bipolar disorder) and vitamin B12 deficiency.
If memory loss is affecting activities of daily life or is accompanied by other symptoms, it is necessary to contact your doctor who will review your history and symptoms and provide appropriate treatment.
