A comparative study was carried out between a control group and different patient subgroups suffering from psychosonratic disorders: headache, insomnia and loss of consciousness due to neurocirculatory dystonia.
Different personality questionnaires (Minnesota Multiphasic Personality Inventory, Sensation Seeking Scale, Susceptibility to Punishment Scale), neurobioelectric parameters (Hjörth descriptors, alpha percentage, P100, N120 P200 of visual evoked responses) and platelet monoamine oxidase B (using phenylethylamine as substrate) were evaluated.
The results show a significant increase in anxiety indicators (at a psychometric and bioelectric level) in the headache and insomnia groups. MAO B activity was higher in patients, especially in the insomniac group; but no significant differences were found in any of the groups studied.
