Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke.
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 ...
Sleep quality issues in early middle-age are associated with accelerated brain aging and cognitive problems later in life, according to new research. Sleep problems in 30s and 40s may add extra ...
A normal brain (left) and one with advanced CTE (right) Specialty: Neurology, psychiatry, sports medicine: Symptoms: Behavioral problems, mood problems, problems with thinking [1] Complications: Brain damage, dementia, [2] aggression, depression, suicide [3] Usual onset: Years after initial injuries [2] Causes: Repeated head injuries [1] Risk ...
The specific causes of neurological problems vary but can include genetic disorders, congenital abnormalities or disorders, infections, lifestyle, or environmental health problems such as pollution, malnutrition, brain damage, spinal cord injury, nerve injury, or gluten sensitivity (with or without intestinal damage or digestive symptoms).
Compounding this is the proven dissociation between objective performance and subjective alertness; people vastly underestimate the effect that sleep deprivation has on their cognitive performance, particularly during the circadian night. [56] Many of acute sleep deprivation's effects can be countered by napping, the longer the more beneficial ...
When this persists over an extended period of time, one may be said to be suffering from PTSD. Examples of events that could lead to the onset of PTSD are war, rape, assault, and childhood neglect. [57] [58] It is estimated that approximately 8% of Americans may have this disease which can lead to long-term problems. [59] Shell shocked soldiers
CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is a loss in brain volume over time. [20]
