HIgh levels of what are found in PD
Catecholamines and MAO
Over stimulation of what in PD
Beta-adrenergic nervous system
Tendency to hyperventilate is associated with what disorder
PD
Concordance rate among 1st degree relatives in PD?
10-25% - only 1-3% in controls
70% of sufferers of PD show what ______infused in their blood. Why?
- Sodium(Na) lactate - They produce a large NE increase in susceptibles
2 differences b/w PET data from lactate positive infusers and normals
- higher levels of brain metabolism - higher activity in non-dominant hippocampal area
List four differences b/w PD patients and normals
-Increased sympathetic tone -Slower adaptation to repeated stimuli -Strong ANS responses to moderate stimuli -50% have mitral valve prolapse (thought to be genetic)
Mital valve prolapse can Can produce some symptoms of PD in non-PD individuals including
Heat rate increase respiration increase
Psychodynamic approach to etiology of PD
Reoccurrence of separation anxiety
