Anxiety is a negative mood state characterized by physical symptoms of physical tension and apprehension about the future. (American Psychiatric Association, 1994; Barlow, 2002).

A moderate level of anxiety can help people to perform certain tasks. However, there is a distinction between healthy anxiety and pathological anxiety. The problem arises when emotions come to mind in situations in which neither fight nor flight is appropriate behavior. Our thoughts are racing, your muscles tense, breathing, our emotion is negative, but we have to fight or flee. Over time, this anxiety can become maladaptive and chronic and the result is that anxiety becomes a source of anxiety disorders.

Biological causes of anxiety disorders

There is increasing evidence that inherited a tendency to be tense or nervous, but as with most psychological disorders, there appears to be a single gene that produces anxiety, but a set of small contributions of many genes in various areas of the chromosome that makes us vulnerable to anxiety.

Anxiety is also associated with brain circuits as GABA system and benzodiazepine. The noradrenergic and serotonergic systems have also been associated with anxiety according to studies, and all is one, moreover, the CRF system , That activates the HPA axis (hypothalamic – pituitary – adrenal) and has great effects on brain areas involved in anxiety.

Treatment Options

Pharmacotherapy: The main advantages of this treatment are that it provides a significant and rapid relief. However, the main drawback is that undesirable side-effects and can induce negative cognitions if the patients had improved as a result of an external agent. It also reflects a significantly higher risk of relapse than those who come to psychotherapy.

Psychotherapy: in the literature practically only refers to the cognitive behavioral therapy (TCC) for being the most widely used and proven effective. Their actions are achieved through the acquisition of skills and control of the confrontation and fears, which often results in a greater sense of ownership of the therapeutic results, leading to more solid and lasting changes. Implies a lower rate of late relapses and enhances self-esteem faster than medication. Among the disadvantages is the greater investment of time and effort by the patient and clinician and a longer wait to relieve anxiety to any significant degree.

Combination therapy: the advantages of each can complement and offset some of the disadvantages associated with each therapy alone. Drug therapy provided psychotherapy to treat disorders associated or reduce acute anxiety and paralyzing, that otherwise would prevent participation in the TCC. Finally, psychotherapy, pharmacotherapy provided to encourage compliance with this or soften the withdrawal of the drug in question. Keep in mind that the combined treatment of an increased time required, cost and collaboration among clinicians who share treatment.

Medication for anxiety

Among the most commonly used medications, we find the benzodiazepines and tricyclic antidepressants. The latter can take up to four weeks to show its effects although perceived a significant clinical improvement. Act to increase the functional activity of norepinephrine and serotonin. Benzodiazepines, however, can become effective from 15-30 minutes. Due to its addictive nature, it is recommended to use this type of drug for extended periods and with great care given to people at risk of substance abuse.
