Busy Lifestyle Syndrome (BLS)

This is a real disorder which causes forgetfulness and lack of concentration in people who take in too much information daily.
A good example of Busy Life Syndrome happens when you can't remember why you just walked into the kitchen or room.

The syndrome was Coined by Scottish researchers to describe this type of memory loss.
It is commonly seen among women; Hard working mums, wives, nurses etc. Can also be seen in Men. Initially it was common among the adults, but now seen in the young.

Causes
According to a Glasgow-based clinical trials company, the syndrome is caused by hectic lives bombarded with information overload from Mobile  Phones, TV, radio, internet, schools, work etc.
The more things we do and see, the more likely we are to forget things.

Another major cause of Busy Life Syndrome is Sleep deprivation; sleeping less than 6hours at night.

Your brain knows you’re unlikely to need to remember a menial task such as going upstairs to get a book in a few hours, so it erases the memory to make room for more important stuffs which you do everyday. Thus sometimes you can't remember why you walked into the room.

Pathophysiology

When you limit the rest time you force the brain to produce excitatory neurotransmitters such as norepinephrine (which is related to the autonomous system to keep you alive), glutamate (which is involved in memory processes, which produces pleasure), dopamine and acetylcholine vitalize handles muscles.
Your body experiences a sense of pleasure that limits us and keeps us stressed, i.e., a situation that is addictive it involves memory loss and lack of concentration.

Signs and Symptoms
Forgetfulness and lack of concentration.

It should be noted that "forgetting" is part of how a healthy brain works. So it should be little surprise that useful things sometimes get deleted among the constant memory-dumping that our brains do as everyday housekeeping.

If your brain did not forget things, you would continually be recalling all kinds of useless information. It would bury you in mental clutter.
Forgetfulness in Busy Life Syndrome should be differentiated from that seen in early onset of Dementia.

The following examples can be seen in Busy Life syndrome
    Forgetting what you went upstairs for.
    Taking several minutes to recall where the car is parked.
    Forgetting to call a friend back while working from home with misbehaving children.
    Putting things down and being unable to find them soon after.
    Forgetting something trivial a friend mentioned the day before.
    Forgetting the name of someone you’ve just met. 
    Briefly forgetting the word for something — the ‘thingamabob’ moment.

The examples below can be seen in early onset of dementia and they are not symptoms of Busy life syndrome.

    Multi-tasking becomes difficult
    Problems negotiating familiar places, such as you regularly can’t find your vehicle in the car park.    
    Forgetting the names of close relatives and friends.
    Problems recognizing faces, colors, shapes and words. 
    Repeating the same question asked half an hour previously.
    Changing personality.
    Finding that you’ve left objects in the wrong place, such as keys left in the lock, and not remembering leaving them there.

Differential Diagnosis
Alzheimers Disease.

Treatment
