forgetting is the disorder of memory.
when we forget something it means the removal of data from our memory.
there are some theories of forgetting.
deacay theory takes place when we donot use the data feeded in our memory.for instance if we watch a movie.. and never recall it then if aftersometime we come across the same movie we wont be able to remember the story,but the chracters will be noticeable.
interference theory takes place when information stored starts to interefere with each other.
there are two types of interferences
retroactive interference and proactive interference.
Retroactive inhibition is the decreased ability to recall previously learned information, caused by the learning of new information.When new material is similar to the older, the tendency to forget previous knowledge increases. One way to reduce retroactive inhibition is to refrain from teaching closely related concepts in a short period of time.
Proactive inhibition is the decreased ability to recall newly learned material,caused by the learning of previous material.
motivational forgetting takes place when we suppress our bad memories,into the sub-consious.memories which are not endurable and when reminded cause fear and pain.
Forgetfulness can be a normal part of aging. As people get older, changes occur in all parts of the body, including the brain. As a result, some people may notice that it takes longer to learn new things, they don’t remember information as well as they did, or they lose things like their glasses. These usually are signs of mild forgetfulness, not serious memory problems. Some memory problems are related to health issues that may be treatable. For example, medication side effects, vitamin B12 deficiency, chronic alcoholism, tumors or infections in the brain, or blood clots in the brain can cause memory loss or possibly dementia .Some thyroid, kidney, or liver disorders also can lead to memory loss. A doctor should treat serious medical conditions like these as soon as possible.Emotional problems, such as stress, anxiety, or depression, can make a person more forgetful and can be mistaken for dementia. For instance, someone who has recently retired or who is coping with the death of a spouse, relative, or friend may feel sad, lonely, worried, or bored. Trying to deal with these life changes leaves some people confused or forgetful. The confusion and forgetfulness caused by emotions usually are temporary and go away when the feelings fade. The emotional problems can be eased by supportive friends and family, but if these feelings last for a long time, it is important to get help from a doctor or counselor. Treatment may include counseling, medication, or both.
A complete medical exam for memory loss should review the person’s medical history, including the use of prescription and over-the-counter medicines, diet, past medical problems, and general health. A correct diagnosis depends on accurate details, so in addition to talking with the patient, the doctor might ask a family member, caregiver, or close friend for information.
