Sensory Overstimulation; 'Flooding'
Flooding occurs after brain injury because the brain's 'filters' no longer work properly.
Many brain injury victims experience sensory overload of the brain.

- odor (enhanced sense of smell)
- own thoughts
- multitude what is said or asked
In overstimulation panic feelings can take possession of the brain-injured. Someone may be sweating, have tremors, can be vomiting, and thinking is difficult.
These are the basic reactions of the body to survive in a situation that is perceived as very dangerous. It is also called the fight or flight response. The one man shall flee from the overstimulation of the noise or stimulus of the moment. The other man will be out of impotence. Most of them are very upset first.
The basic emotion of fear and the ensuing responses are generated and directed by the amygdala. The amygdala is part of the oldest part of the brains, the limbic system. This system is a kind of emotional sentry. All that matters is survival. If there is danger, directly adrenaline, noradrenaline and cortisol are released into the body to flight, fight or freeze.
At the same time, the neo-cortex also called the rational mind will stop the mind from thinking. Because, after all, in threatening situations lacking the time to decide what the best plan of action will be.
A rapid response of the amygdala thus ensures that we can avoid the danger before we realize that we find ourselves in such a situation.
Summary: By overstimulation people are no longer able to rationally deal with the situation. Fear prevails and the amygdala creates a fight-flight-or freeze reaction.
VIDEOS : sensory overstimulation
This first video shows a two minute simulation of how sensory overstimulation 'feels'. It is made by someone who experiences overstimulation of the senses every day, due to bad filtering caused by braindamage. Therefore she lives isolated to escape for sounds, bright light, visual stimuli etcetera.
SOUNDS
Overstimulation by sounds occurs in background noise where the sounds can not be cut out. Not being able to follow a conversation with multiple sounds. Noise intolerance. Irritation in rhythmic sounds, ticking of a clock or buzzing fluorescent lighting. Shoe steps on a wooden staircase or wooden floor, squeaky doors, etc.
Many complaints are reminiscent of or equal to hyperacusis. Hypersensitivity to sound. Many people also experience pain in sound.

PICTURE
Sensory overstimulation occurs at seeing patterns or colors. Seeing a variety of nice stuff at home. Letters that are too close to each other with no blank lines. Seeing movements, seeing moving hands or people who wiggle their legs but also seeing a multitude of people. Seeing a multitude of some objects. Seeing details like prints, shades, bricks etc.
Even seeing unordered higgledy-piggledy or 'for sale' articles can give too much stimuli for the brain to see it in a shop. Like a bargain basement, not stacked shopping baskets, etc., etc.

LIGHT
Sensory overstimulation by light occurs in reflected light, in certain lights (halogen! fluorescent lighting!), Backlight or changes of shadow and light while driving, bright light, lots of light, flickering candles etc.

Notorious is car driving on a road where are many trees and low standing sun behind the trees.
FEELING

Pretty much as what you experience by watching these pictures:
SMELL
Sensory overstimulation by smell can come about by enhanced sense of smell and can include nature smells, food smells, natural odors, body odors, perfumes and deodorants (including nursing staff and caregivers!)

Chronic overstimulation
Chronic overstimulation is not healthy. It is pure stress.
Chronic overstimulation is not healthy. It is pure stress.
The endocrine system changes (increased stress hormone level) and long-term chronic overstimulation also changes ones nervous system. Actually this can even make an individu more sensitive to overstimulation than he already was. Symptoms might be physical symptoms like headaches, stomach problems, decreased resistance, sleeping disorders , extreme fatigue, or even depression, burnout or anxiety.
