It is thought that it may be caused by the body's inflammatory response to surgery, stress hormone release during surgery, ischemia, or hypoxaemia. [5] [6] Post-operative cognitive dysfunction can complicate a person's recovery from surgery, delay discharge from hospital, delay returning to work following surgery, and reduce a person's quality ...
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
Brain injury will commonly be accompanied by acute swelling, which impairs function in brain tissue that remains alive. Resolution of swelling is an important factor for the individual's function to improve. The greatest factor in functional recovery after brain injury comes from the brain's ability to learn, called neuroplasticity. After ...
These hormone-producing tumors may need adrenalectomy. Additionally, adrenal tumors that are larger than 4 centimeters in size, regardless of whether they produce hormones, also require adrenalectomy due to increased risk of adrenal cancer. Rarely (5–12%), the adrenal tumor may be cancerous (adrenocortical carcinoma), requiring adrenalectomy.
Addison's disease, or primary adrenal insufficiency, is an uncommon chronic illness characterized by insufficient production of cortisol and aldosterone by the adrenal glands. [17] Chronic primary adrenal insufficiency is typically characterized by an extended period of malaise, fatigue, anorexia, weight loss, joint and back pain, and skin ...
Glasgow Coma Scale (GCS) is the most widely used scoring system used to assess the level of severity of a brain injury. This method is based on the objective observations of specific traits to determine the severity of a brain injury. It is based on three traits: eye opening, verbal response, and motor response, gauged as described below. [35]
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins.
If sympathetic activity is elevated for an extended time, it can cause weight loss and other stress-related body changes. The list of conditions that can cause sympathetic hyperactivation includes severe brain injury, [ 56 ] spinal cord damage, [ 57 ] heart failure, [ 58 ] high blood pressure, [ 59 ] kidney disease, [ 60 ] and various types of ...
