Due to this increased use and demand of high-quality EEG devices, there are now numerous companies that. read more to examine the optic nerve, which bulges when the pressure within the skull is increased. Electroencephalography (EEG) is a technique with over a hundred years of history, and while it was originally used more strictly in the fields of psychology, medicine, and neuroscience, it is widely used today in gaming, human-computer-interaction, neuromarketing, simulations, and beyond.

However, some eye disorders cause few or no symptoms in their early stages, so the eyes should be checked regularly (every 1 to 2. For example, doctors use an ophthalmoscope Ophthalmoscopy A person who has eye symptoms should be checked by a doctor. The medical history and neurologic examination help doctors determine whether herniation is a risk. Herniation puts pressure on the brain and may be fatal. Common causes of head injuries include falls, motor vehicle crashes, assaults, and mishaps during sports and recreational activities.

As a result, the brain may shift and be pressed through one of the small openings in the relatively rigid tissues that separate the brain into compartments (called herniation Herniation: The Brain Under Pressure Head injuries that involve the brain are particularly concerning. In such cases, a spinal tap may suddenly reduce pressure below the brain. read more damages nerves throughout the body, starting with those in the feet.Дoctors do not do a spinal tap when the pressure within the skull is increased, for example, when there is a mass (such as a tumor or abscess) in the brain. read more ), as when diabetes Nerve damage in diabetes People with diabetes mellitus have many serious long-term complications that affect many areas of the body, particularly the blood vessels, nerves, eyes, and kidneys. Infections, toxins, drugs, cancers, nutritional deficiencies, diabetes, autoimmune disorders, and.

The cause of most cases of carpal tunnel syndrome is unknown. If nerve conduction is slow, the cause may be a disorder that affects one nerve, such as carpal tunnel syndrome Carpal Tunnel Syndrome Carpal tunnel syndrome is a painful compression (pinching) of the median nerve as it passes through the carpal tunnel in the wrist. read more, or diphtheria Diphtheria Diphtheria is a contagious, sometimes fatal infection of the upper respiratory tract caused by the gram-positive, rod-shaped bacteria (see figure How Bacteria Shape Up) Corynebacterium diphtheriae.
