Brain works like a computer. The way a computer saves data, similarly brain also saves data. Memory is the term used to describe a group of informations stored in the brain. These can be pulled back or recalled at any time required.
There is long term memory and short term memory. In long term memory, the informations are stored for a long time that needed for the day to day life activities. But short term memory stores the information for a short period of time like memorizing a chapter for examination.
Brain has different areas that stores specific kind of information. One memory or information is broken down into different parts before storing. As and when it is recalled, these different pieces are brought together along with the cross-references, just like how the search engine works.
It is believed that as the age progresses, mental ability and memory starts declining. It mostly starts from the age after 50. Short term memory is affected first and it becomes difficult to cope with day to day activities. The brain functions will become slow and as a result multitasking or doing many things at a time gets affected.
Forgetting a recent conversation, misplacing things or forgetting names are very common. This may be due to stress and tiredness and may not necessarily amount to a serious memory problem. Issues such as using inappropriate words, getting lost in familiar places, having difficulty in reading a book or newspaper might require a medical assistance.
Forgetfulness may occur due to side effects of medication such as sleeping pills, painkillers, antihistamines, blood pressure and arthritis medication, muscle relaxants etc or vitamin B12 deficiency or alcohol over consumption etc. Emotional problems, such as stress, anxiety, or depression, can also lead to memory loss.
