Final answer:
Impaired cerebral autoregulation can be caused by various factors including neural, endocrine, and autoregulatory mechanisms. Hypertension, hemorrhage, and shock are also likely to affect cerebral autoregulation.
Step-by-step explanation:
Impaired cerebral autoregulation can be caused by various factors, including neural, endocrine, and autoregulatory mechanisms. Neural mechanisms involve the cardiovascular centers in the medulla oblongata, baroreceptors in the aorta and carotid arteries, and chemoreceptors that monitor blood levels of oxygen, carbon dioxide, and hydrogen ions. Endocrine controls include hormones like epinephrine, norepinephrine, ADH, and the renin-angiotensin-aldosterone mechanism. Autoregulation is the local control of vasodilation and constriction through chemical signals and the myogenic response. Disorders such as hypertension, hemorrhage, and shock can also impact cerebral autoregulation.
