During an epileptic seizure the regulatory system that maintain the normal balance between stimulation (excitation) and dampening (inhibition) of nerve cell activity break down (Devinsky, 2008). Epilepsy is primarily known for causing convulsions. But, seizures can prompt a large variety of symptoms, from staring to falling to fumbling with clothes. Seizures are divided into two major categories -- focal seizures and generalized seizures. However, there are many different types of seizures in each of these categories.
Now the patient is hyperkalemic from the metabolic acidosis causing dysrhythmias leading to cardiac arrest. (Excited Delirium Strikes Without Warning). Dopamine can be a self-induced problem by taking illegal drugs that block the uptake of dopamine or it can be something the body produces too much of on its own. Wesley goes on to say that, “A large number of these patients who suffer from excited delirium have pre-existing psychiatric conditions…” (Excited Delirium Strikes Without
Hallucinogens Certain hallucinogens have been used for thousands of years as spiritual tools by cultures around the world. The shamans of Mesoamerica and the Amazon used a variety of hallucinogenic plants to send them on epic spiritual journeys. There is evidence of cannabis consumption and documentation of psychoactive plants and fungi used in Stone Age Europe as well as more recent use by pagan religions. Popularized by the ‘60s counterculture, they are used mostly for recreational purposes now. Hallucinogens in general have low addictive potential, but if abused can become psychologically addictive.
Hemorrhagic stroke occurs when a blood vessel located in the brain starts to either leak or rupture. This is usually caused by high blood pressure and weakened walls of the vessel caused by an aneurysm. There are two types of hemorrhagic stroke, intracerebral and subarachnoid. An intracerebral hemorrhage is when an artery in the interior of the brain bursts and the blood moves into the surrounding area causing damage. In a subarachnoid hemorrhage, a blood vessel also bursts, but instead of being on the interior, the vessel is located near the surface of the brain.
TBI or concussions can cause long-term or short-term brain damage among a long list of effects. It is dangerous but the effects can be cured or altered by early detection. TBI or traumatic brain injury being synonymous with concussion is a blow or jolt to the head that disrupts brain function. There have been many different, yet the same, definitions of concussion over the years, decades and even centuries. The Oxford English Dictionary defines concussion as the action of violently shaking or agitating; particularly, the shock of impact or injury caused to the brain, spine, or other part by the shock of a heavy blow, fall, etc.
Visual processing, body movement, auditory process and language are all directly affected. 4. The brain is an entire system; if one part is not working at the normal level then the rest will be affected which can cause confusion, hallucinations, delusions and false beliefs. Other factors can cause
According to Brant, W. (2007) “Patients may present with virtually any neurologic defect, but they most commonly present with limb weakness, paresthesia, vertigo, and visual or urinary disturbances”. A lot of times the initial symptoms are “sensory disturbances, weakness, visual loss, abnormal gait, diminished dexterity, diplopia, ataxia, vertigo, or sphincter disturbances” (Brust, J. 2012). There can also be other more general symptoms such as malaise, fatigue, or headache caused by the initial disruption in the CNS (Brust, J. 2012).
Migraine headaches, other body changes that affect brain function, medications, depression, family problems and other physiological changes may mimic brain damage. Any changes in interpersonal behavior, attention, foresight and an inhibition of appropriate behavior point to the frontal lobes, usually with damage to the olfactory
This is one type of mental illness that about 1 in 100 people will develop, which is also about 24 million people across the world. This disorder can be caused by brain abnormalities, genetic factors, and or psychological factors. There are different types of schizophrenia; paranoid, disorganized, catatonic, undifferentiated, and residual. Paranoid schizophrenia causes one to have hallucinations and delusions. Disorganized schizophrenia is when their behavior or speech is much unorganized and could cause inappropriate emotion.
Psych 213 Dr. Les White April 9, 2012 Major points the article covers or raises “The Addicted Brain,” by Nestler and Malenka discussed the brain’s memory of addiction which results from repeated use and subsequently abuse of drugs and alcohol. While very technical and scientific in its detailing of the processes, it was also very insightful in spelling out the brains rewarding of the pleasure that results from drugs of abuse (DOA). It seems that we have known for quite a while why someone feels good when they use DOA, but the article points out that new research is just beginning to understand some of the resulting long term changes in the brain. Even though the pleasurable effects of using a particular drug aren’t as strong as they
