Memory Loss
Memory loss is the loss of memory, the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. Memory loss is usually described as forgetfulness, absent-mindedness, or a physical or mental disorder such as amnesia. Memory loss can be partial or total, and it is normal when it comes with aging. Sudden memory loss is usually a result of brain trauma and it may be permanent or temporary. When it is caused by medical conditions such as Alzheimer's disease, the memory loss is gradual and tends to be permanent.
Memory disorders are the result of damage to neuroanatomical structures that hinders the storage, retention and recollection of memories. Memory disorders can be progressive, including Alzheimer's disease, or they can be immediate including disorders resulting from head injury.
Brain trauma is not the only factor that can cause sudden memory loss. It may appear as a side effect of statin drugs that are used as treatment for those who have hypercholesterolemia. Major causes of sudden loss of memory are strokes. Other causes are long lasting and recurrent illnesses such as meningitis or epilepsy. Either temporary or permanent memory loss can also result from chemical imbalances, exposure to toxic substances, allergies, vitamin deficiencies (such as those caused by alcoholism), or extreme mental illness (major depressive disorder).
