['Hyperventilation syndrome': often an easy to treat panic disorder]. / 'Hyperventilatiesyndroom': veelal goed behandelbare paniekstoornis.

Three patients, 2 men aged 35 and 26 years and 1 woman aged 41 years, had acutely occurring attacks, accompanied by diverse somatic complaints, and were diagnosed with hyperventilation syndrome. They recovered only when the complaints were recognised and treated as a panic disorder. Hyperventilation and the decrease of CO2 in the blood do not explain the symptoms and complaints in patients with panic disorder, a psychiatric disorder with a good prognosis. Treatment consists of cognitive behavioural therapy or a selective serotonin re-uptake inhibitor in the case of panic disorder and of a combination of those two treatments in the case of panic disorder with agoraphobia. Breathing exercises can form part of the behavioural therapy but not because the disorder is due to faulty breathing habits.
