Headache headaches nervous system dysfunction

Central nervous system dysfunction. Acute effects of exposure to acrylonitrile generally involve the central nervous system. Symptoms of acrylonitrile exposure include headache, nausea, dizziness, and general weakness. The animal studies cited above suggest possible carcinogenic effects of acrylonitrile on the central nervous system, since rats exposed by either inhalation or ingestion have developed similar CNS tumors. 

In some conditions, the pain appears to be caused by a complex mixture of nociceptive and neuropathic factors. An initial nervous system dysfunction or injury may trigger the neural release of inflammatory mediators and subsequent neurogenic inflammation. For example, migraine headaches probably represent... 

The main varieties of adverse effects attributed to cimetidine relate to its antiandrogenic properties and its actions in sufficient concentrations on the central nervous system. There is also a spectrum of drug interactions, mainly attributable to inhibition of hepatic CYP isoforms, but they only have clinical consequences under special circumstances. Occasional adverse effects, which are generally minor, include bradycardia and conduction defects, thrombocytopenia, neutropenia, interstitial nephritis, mild hepatic dysfunction, and headache. Intestinal infection due to loss of the gastric acid barrier also occurs, and myalgia, fever, monoamine oxidase-Uke interactions, and neuropathies have been well documented occasionally. Allergic reactions, such as bronchospasm, have rarely been described. Anaphylaxis with recurrence on rechallenge is on record, as are asthma and skin effects. 

Noise is a vicious stimulus, when people are exposed to noise for a long time, the noise may stimulate the central nervous system, cause autonomic nervous system dysfunction and with the excitement and inhibition of cerebral cortex out of balance and reflex abnormalities, some symptoms appear, such as dizziness, headache, tinnitus, dreamy, insomnia, nervousness, memory loss, distraction, and even mental disorder appears in severe cases (Tian Zhou 2010, Liu 1999). 

The sequence of somatic dysfunctions that were treated is significant in that the osteopathic thought process should include an attempt to restore normal function on a systemic basis as well as treating the local area of dysfunctions (treat the whole patient). With edema in all four extremities, lymphatic techniques become more prominent in the treatment plan. The headache symptom associated with increased cervicocran-ial junction muscle tone is indicative of an increase of sympathetic tone, probably secondary to nociceptive (pain) input. Balanced ligamentous tension, counterstrain, and cranial techniques are indirect techniques that can achieve reductions in muscle tone and reduce facilitation in the nervous system restoring a more normal balance. 

Acute lead poisoning in humans may cause severe dysfunction of the kidney, reproductive system, liver, brain, and central nervous system leading to sickness or death. Lead poisoning from environmental exposure is thought to have caused mental retardation in many children. Mild lead poisoning causes anemia. The victim may have headaches and sore muscles, and may feel generally fatigued and irritable.
