It is a condition that you may not know about, you may not realize you have, but it can be very serious for your immediate and long-term physical and mental health.
Hypoperfusion (shock) is the inadequate perfusion of the body’s tissues, resulting in an inadequate supply of oxygen and nutrients to the body’s tissues.
Perfusion is the term used to describe the blood supply to the various organs. Hypo is the Greek prefix for below. Hypoperfusion is the lack of blood supply to an organ. This can be a very serious problem. Depending on the severity and duration of the blood deprivation, it can cause physical problems, pain, and cell death.
Hypoperfusion can occur anywhere in the body as a result of a variety of conditions. It is common in the extremities, such as the hands and feet, the kidneys, the skin, and the heart. It can be the result of external conditions, numerous diseases or physical activities and conditions of the spine.
Blood carries oxygen and nutrients to the cells of the body. Any drop in the supply of these life-sustaining substances results in decreased cellular performance and, if severe enough, cellular damage that the body may or may not repair.
If the reduction is severe and acute, it is known as ischemia or shock. One cause of stroke is severe hypoperfusion in the brain.
One of the most serious places for hypoperfusion to occur is in the brain. This condition is known as cerebral hypoperfusion. A reduction in blood flow in the brain can have a myriad of health effects, depending on which areas of the brain are affected.
Hypoperfusion can be a condition that you experience without realizing that your physical and mental abilities are diminished. Even less likely you will make the connection between neck pain and your slightly diminished abilities or mood swings.
Prolonged inattention to this condition could lead to increased hypoperfusion symptoms and possibly an increased risk of actual brain cell damage due to long-term blood flow problems.
The most noticeable symptom you may have is pain in your neck and upper back. Many people simply choose to live with their pain, and accept it as an unfortunate but normal part of life.
However, ignoring treatment for this pain could cause you physical and mental harm. It could possibly lead to more serious problems in the future if left untreated.
If you suffer from chronic neck and / or upper back pain, the best thing you can do for yourself is to have an experienced professional spy examine you.
Subcortical ischemic vascular dementia is a relatively common form of dementia. The anatomical changes of aging in the cerebral arteries predispose the elderly to the effects of hypotension .
Depending on their circulatory pattern, particular regions of the brain are susceptible to hypoperfusive ischemic lesions. These regions include the periventricular white matter, basal ganglia, and hippocampus.
Disruption of prefrontal-basal ganglionic circuits important for cognition and memory may be the result of these injuries.
Hypotension and hypoperfusion explain the high risk of developing cognitive impairment and vascular dementia in older patients affected by orthostatic hypotension, congestive heart failure, as well as in those undergoing surgical procedures such as hip and knee replacement and coronary artery bypass graft (CABG).
Recognition of the susceptibility of elderly subjects to hypoperfusion-induced brain injury should result in appropriate preventive measures and better treatment.
Dizziness, vision changes or temporary loss of vision, headaches, nausea, and fainting are some of the symptoms that can result from reduced blood flow in the brain.
Cognitive impairment, attention disorders, depression, emotional instability, uncoordinated motor functions, visual, auditory and spatial relationship problems (detecting where your body is in space and placing it in the correct position) can also be a consequence of decreased blood flow to certain parts of the brain.
Both the frontal and parietal areas of the brain control some vitally important functions. The parietal zone controls sensory input from the rest of the body, spatial sense, and vision.
The frontal zone is key in the coordination of voluntary motor skills, memory management and mood control, all three are fundamental in the way we function socially and assess mental health.
Orthostatic cerebral hypoperfusion syndrome
Orthostatic cerebral hypoperfusion syndrome is a new syndrome associated with orthostatic hypoperfusion. Patients with orthostatic cerebral hypoperfusion syndrome have stable orthostatic blood pressure, heart rate, and respiratory pattern, and still have a reduced orthostatic cerebral blood flow rate .
A decrease in the speed of orthostatic cerebral blood flow can cause cerebral hypoperfusion and central nervous system symptoms, including dizziness.
Orthostatic cerebral hypoperfusion syndrome affects a wide range of age groups, with more women than men affected. However, this could be due to referral bias and needs to be confirmed in further studies.
Several comorbidities have been found in orthostatic cerebral hypoperfusion syndromes, hypertension being the most frequent (21%). Whether this is a true association between hypertension and orthostatic cerebral hypoperfusion syndromes or whether it reflects shunt bias should be assessed in further studies.
Shock is a life-threatening medical condition of low blood perfusion to tissues that results in cell injury and improper tissue function.
Typical signs of shock are low blood pressure, rapid heart rate, signs of poor end-organ perfusion (eg, low urine output, confusion, or loss of consciousness), and weak pulses.
During the initial stage, the hypoperfusion state causes hypoxia. Due to the lack of oxygen, the cells carry out the fermentation of lactic acid.
Since oxygen, the terminal electron acceptor in the electron transport chain, is not abundant, this slows the entry of pyruvate into the Krebs cycle, resulting in its accumulation. The accumulation of pyruvate is converted to lactate by lactate dehydrogenase and therefore lactate accumulates (causing lactic acidosis).
A recent study has shown that there is a probable link between spinal health and hypoperfusion in the brain.
29 women and 16 men with varying degrees of chronic neck pain, chronic upper back pain, or both, were examined with a computed tomography scanning system known as single photon emission computed tomography.
This technology can show blood flow in the brain. The researchers examined eight areas of the brain to see if there was any correlation between vertebral subluxation and cerebral hypoperfusion.
Vertebral subluxation is a condition in which the position of individual vertebrae in the spine can be slightly misaligned. The vertebrae rest between discs of softer tissue that provide the spine with the ability to move and flex.
The discs also provide spaces for individual nerves to connect to the spinal cord, which connects to the brain at the base of the skull. Those nerves connect to every part of the body.
They provide information about the body to the brain and instructions from the brain to the body. In effect, these nerves that make up the nervous system control, coordinate and regulate the function of every cell and organ in the body.
The health of the spine is vitally important to the nervous system’s ability to function properly.
Any inflammation or constriction in the spine can have deleterious effects on the nervous system, including the way the peripheral nervous system serves and interacts with the brain.
Patients received a standard neck disability index (NDI) assessment. They were also examined for the number of painful or blocked spinal points (vertebral subluxations) they had.
Based on the responses to the cervical disability index and spinal examinations, they were classified into three categories: mild, moderate, and severe.
The mild group consisted of 14 patients. Single photon emission computed tomography examination indicated that brain perfusion was normal in all eight measured areas.
The moderate group included 16 patients. Results of the single photon emission computed tomography scan showed that brain perfusion in this group was 20 to 35 percent below normal. The most affected areas were the frontal and parietal areas of the brain.
The severe group had 15 patients. The results of the single photon emission computed tomography scan showed that brain perfusion is 30 to 45 percent below normal. Again, the reduced blood flow was mainly in the frontal and parietal areas.
The conclusion of the study was: “In this group of patients with neck and / or upper back pain, neck disability index scores strongly predicted cerebral hypoperfusion.”
