Given that the first stage of a seizure is strongly altered perception of sensory information, it seems to follow that the sensory area is affected first. In fact, epilepsy is strongly associated with sensory (and motor discussed next) cortex, which lies just behind the central fissure on each side of the brain. Posttraumatic epilepsy, a common complication of severe head injuries, may be the result of scar tissue formation near the sensory cortex. The abnormal firing spreads from the sensory area to an area for motor control. The second stage of a seizure is ictus and is characterized by convulsions.
The loops involves the orbital frontal cortex which picks up on situations that we need to worry about and then sends this message on to the Caudate Nucleus which describes whether or not the message is important and if it deems yes, the message is passed on to the thalamus, which acts upon the received message. However in a faulty brain such as someone with OCD, the Caudate Nuclei has tissue damage and so whenever it receives information from the Orbital Frontal Cortex, it deems the message as important and therefore an issue that needs to be dealt with. Because of this sufferers of OCD get compulsions such as a repeated washing of their
1. Explain how the use of substances alters a person’s state of consciousness, including depressants, stimulants, and hallucinogens. Include in this explanation what happens to the neurotransmitters and body chemicals as well as how you might recognize if a person at work or in your family is in an altered state of consciousness due to the influence of drugs. Drugs can either enhance a particular neurotransmitter’s effect (an agonist drug) or inhibit it (an antagonist drug). Depressants act on the central nervous system to suppress or slow bodily processes and to reduce overall responsiveness.
A person with polycystic kidney disease will experience symptoms as a result of the damage caused by cysts (fluid-filled sacs) that develop in the kidneys. The signs and symptoms of polycystic kidney disease will vary based on the type of the condition a person has. For example, symptoms of autosomal dominant polycystic kidney disease include headaches and pain in the back and the sides. Polycystic kidney disease symptoms that may occur in someone with acquired cystic kidney disease include urinary tract infections and
Explain how individuals experience discrimination due to misinformation, assumptions and stereotypes about mental ill health. 2.2. Explain how mental ill health may have an impact on the individual including: a) psychological and emotional b) practical and financial c) the impact of using services d) social exclusion e) positive impacts. 2.3. Explain how mental ill health may have an impact on those in the individual’s familial, social or work network including: a) psychological and emotional b) practical and financial c) the impact of using services d) social exclusion e) positive impacts.
The drug also alters one's perception of pain, usually resulting in extreme emotional responses. In the long term codeine can permanently affect the way one's nervous system triggers responses from nerves, resulting in a different perception of pain, touch, and temperature. Repeated use of codeine can also cause bleeding within the stomach, kidney damage, constipation, depression, and in some extreme cases hallucinations or seizures. Stopping codeine consumption abruptly causes withdrawal, usually characterized by runny noses, sweating, muscle twitches and pain, and an irregular
If these neurotransmitters are out of balance, the chemical messages cannot get through the brain properly. This can alter the way the brain reacts in certain situations, causing anxiety. Some parts of our brain chemistry are also involved in generalized anxiety disorder. Most notably the brains of people with generalized anxiety disorder have abnormal levels of serotonin and nor-epinephrine. The most popular treatments for generalized anxiety disorder work to correct this.
Multiple sclerosis Multiple sclerosis This booklet includes- The symptoms of Multiple Sclerosis The impact of Multiple Sclerosis The signs of Multiple Sclerosis What is multiple Sclerosis? Multiple Sclerosis is a disease that affects the brain and the spine, eventually it ends in not being able to control muscles, loss of vision, not being able to balance, and numbness. When you suffer from multiple sclerosis the brain and spine are damaged by the immune system, this is known as an autoimmune disease. The symptoms- The symptoms affect every person differently, they vary on how much damage has been done to the nerves. Some symptoms include: -visual Problems: the visual problems are one of the first to occur normally.
<br> Clinical depression is an illness that effects us psychologically, biologically and socially. It may be brought on by sadness, anger and according to some researchers genetically. Although it is hard to classify clinical depression, at a biological stand point it takes a direct route. <br> Depression is caused by an imbalance of the neurotransmitter serotonin, dopamine and norepinephreine. Neurotransmitters are chemical released by the nerves that deliver messages across a synapsis to another nerve.
