This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Treatment for lightheadedness depends on the cause or underlying problem. Treatment may include drinking plenty of water or other fluids (unless the lightheadedness is the result of water intoxication in which case drinking water is quite dangerous).
A change in the magnitude of the vestibulo-ocular reflex due to vestibular disease can also lead to oscillopsia during rapid head movements. [3] Oscillopsia may also be caused by involuntary eye movements such as nystagmus , or impaired coordination in the visual cortex (especially due to toxins ) and is one of the symptoms of superior canal ...
The cause of the syndrome is unclear. [3] The underlying mechanism is believed to involve excessive excitability of neurons in the right lingual gyrus and left anterior lobe of the cerebellum . Another hypothesis proposes that visual snow syndrome could be a type of thalamocortical dysrhythmia and may involve the thalamic reticular nucleus (TRN).
The causes of frontal lobe disorders can be closed head injury. An example of this can be from an accident, which can cause damage to the orbitofrontal cortex area of the brain. [2] Cerebrovascular disease may cause a stroke in the frontal lobe. Tumours such as meningiomas may present with a frontal lobe syndrome. [11]
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
Many conditions cause dizziness because multiple parts of the body are required for maintaining balance including the inner ear, eyes, muscles, skeleton, and the nervous system. [7] Thus dizziness can be caused by a variety of problems and may reflect a focal process (such as one affecting balance or coordination ) or a diffuse one (such as a ...
A sinus infection can cause facial pressure and pain, as well as nasal congestion and headaches, which are also known as heavy-headedness. [citation needed] New users to specific drugs can cause heavy-headedness. Chronic subjective dizziness (CSD) can be related to heavy-headedness. Nausea and vomiting can cause
