It's almost impossible to accurately pinpoint the underlying causes of anxiety, even though medical practitioners agree that is it's mostly a combination of separate factors like genetic predisposition, brain chemistry, and environmental conditions.
Often the prescribed medications for the treatment of the physical manifestations of persistent depression and anxiety remain something of a mystery even to scientists.
The symptoms of anxiety attack are often much easier to treat than the causal factors themselves.
Fortunately, a proper combination of both psychotherapy and medication has often proved very effective.
In the brain, the nerves communicate with each other through chemicals known as neurotransmitters.
Sometimes, when there is an improper concentration of these chemicals, the correct transmission of messages between brain cells is jeopardized and this may lead to anxiety.
Often, people who suffer from this disorder are already genetically predisposed to it.
So they are more prone to attacks than those from families with no history of any mental illnesses.
Sometimes, a very emotionally difficult life event, such as the passing of a loved one for instance, can be the trigger for abnormally high anxiety levels.
Experiences like these usually result in post-traumatic stress which is another form of anxiety disorder.
One cause of anxiety disorder that isn't widely acknowledged is the post-withdrawal effects of addictive substances such as alcohol, caffeine, or nicotine.
Desisting from these substances, after long periods of use, can therefore leave such a person more prone to anxiety attacks.
Drugs and steroids such as LSD, amphetamines, cannabis, and ecstasy may also cause anxiety.
The possible causes of anxiety are so many and widespread and usually act in combination that it's notoriously difficult to put a finger on an exact cause.
Usually and fortunately, the combination of therapy and medication proves very effective at dealing with this disorder.
