HYPERVENTILATION AND MONOPOLAR AFFECTIVE DISEASE-TYPE DEPRESSION
Journal Title: Acta Neuropsychologica - Year 2011, Vol 9, Issue 1
Abstract
MAD-type depression is a mental disorder with many and various symptoms, which can be classified as emotional, cognitive, motivational, or somatic. These last two are strongly correlated with the cardiovascular system, which is linked with the respiratory system.Material and methods: 98 women diagnosed with MAD (age 27 – 44 years) were examined with the STAI Inventory (X-1, X-2), and then twice more (before and after psychological conversation), using the FlexComp Infinity/BioGraph Infinity (Thought Technology Ltd.) to monitor the plethysmographic wave biosignal (PPG) behavior, along with computer evaluation related to the pulse wave and breathing depth.Results: A high level of fear and hyperventilation measured by PPG produces not only a synchronic component corresponding to cardiac contraction, but also a component related to breathing. Physiological hyperventilation caused by sinus node arrhythmia together with the intensified fear and anxiety characteristic of MAD can be attributed to this phenomenon. This regularity should be taken into consideration in both the diagnosis and therapy of the chronically recurrent and persistent depression characteristic of MAD.Conclusion: More detailed conclusions require the continuation of research on larger subpopulations with excessive lung ventilation in relation to the organism’s metabolic needs.
