To discuss:
The process of how Parkinson patients respond to Valsalva maneuver and how this relate to a common condition in Parkinson patients called orthostatic hypotension, in which blood pressure falls suddenly when the person stands up, leading to dizziness and fainting.
Given:
Recent research indicates that Parkinson disease damages the sympathetic division of the peripheral nervous system. One test for sympathetic division function, called the valsalva maneuver, requires the patient to blow against resistance. A functional nervous system will compensate for the decrease in blood output from the heart by constricting blood vessels.
Introduction:
Valsalva maneuver (VM) was described by Anton Maria Valsalva which he described as the act of the forceful inspiration against a closed glottis after the process of full inspiration. There are several studies related to the complication of cardiovascular changes with respect to Valsalva maneuver

The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?arrow_forward
