The effects of amnesia and its different types

The effects of holding loss and its different lineamentsbrownout is defined as the full or partial loss of entrepot that whitethorn be temporary or long-lasting, causation a portentous inability to remember important information to such(prenominal)(prenominal) a dot that it has moderate to severe effects on persons life (Logsdon). The effects of blackout argon related to the type of amnesia patient is suffering. The most super acid effect is the inability to recall information stored in the long-term shop. in that location be some cases that patient is capable to recall last(prenominal) memories, yet he is unable to create new memories, or even, unable to do both recall past memories and create new ones (Nordqvist, 2009).There are many factors that origin amnesia, which are categorise in constituent(a) and functional. The primitive factors are related to injuries in the brain, and loss of brain cells in the frontal, parietal, and lay lobes. A cause of brain injur y is when it is occurred in car accidents. The breaker point of depot loss usually is proportional to the severity of harm in the brain. In most cases, amnesia is not severe and the obtainy is short-lasting (Nordqvist, 2009). An organic factor of brain injuries is the brain has suffered a virus infection such as encephalitis (inflammation), which the brain tissue is unnatural by a mistaken attack of the immune system, or an insufficient supply of oxygen to the brain due to a heart attack, respiratory distress, or ascorbic acid monoxide poisoning (Nordqvist, 2009). An different factor of brain injury is the abuse of alcoholic drink and drugs, such as sleeping and depressive pills, by a prolonged time, causing holding loss (Crystal, 2010). The functional factors are related to emotional shocks caused by being the victim of a violent crime, child or versed abuse, or being involved in a combat, natural disaster, or a terrorist attack (Nordqvist, 2009).brownout is presented in many types depending on the outcomes occurred to the affected person, or any traumatic event he or she is affected. The future(a) three types of amnesia are related to the effects in the persons memory and the capability to recall information.Retrograde amnesia is the most common type presented in hospitals, television shows, and movies. This is caused by damage in the temporal lobes and curiously the hippocampus (Ellis-Christensen, 2010). Patients with pull back amnesia are unable to recall memories from the past occurred before it is presented, but the ability to form new memories and recall after the start of amnesia is not affected (Wall, 2006).Anterograde amnesia is the reverse-side of retrograde amnesia. This is caused by the damage to the hippocampus or surrounding cortices, disabling memory formation, and often it is permanent if the brain is damaged (Liden, 2010). Patients with anterograde amnesia are unable to form new memories from the point when it is presented and t o recall memories recently form because information is not moved to the long-term memory. However, patients may be able to learn new skills without being taught again because the declarative memory is impair while the procedural memory continues to function (Liden, 2010). Although anterograde amnesia is permanent when brain damage is presented, scientists actually are studying ways to halt neural plasticity, the capability of nerves to form new ways to recover lost functionality, to perform treatments for this and other diseases caused by brain injury (Liden, 2010). transeunt world(prenominal) amnesia is a temporary total loss of memory and the patient affected is unable to recall any information restored in memory. The causes of this disease are uncertain, but some hypotheses establish it could be caused by a reduced blood flow, a traumatic event, stress, or an abnormal type of migraine. This disease tends to reverse itself over time, but the temporary dimout terminate last f or 24 hours or more (Wall, 2006).The following types of amnesia are related to disturbing events, or abuse of alcohol and drugs. traumatic amnesia is caused by a hard blow to the head as a result of a car accident. The person affected may experience a brief loss of consciousness, or even go into a coma. The absolute majority of cases are temporary and it lasts depending of the severity of the injury. Childhood, or infantile, amnesia occurs when the person is unable to recall events from early childhood. The causes could be that this may be associated with language developments, or the possibilities of some areas of the brain were not fully come along during childhood. Wernike-Korsakoffs amnesia is caused by excessive abuse of alcohol, or by malnutrition conjugated to thiamin deficiency. Patients with this disease have poor coordination and loss of feeling in the fingers and toes (Nordqvist, 2009).To diagnose amnesia in a patient, a atomic number 101 exit do an evaluation to dis card other possible causes of memory loss, such as dementia, psychic picture, a brain tumor, or Alzheimers disease. First, the atomic number 101 starts the evaluation with a detailed medical history, including the type of memory loss, when the problems started and how they progressed, factors that started amnesia, such as a head injury or a traumatic event, family history peculiarly of neurological disease, use of medical specialty or alcohol and drugs, history of seizures, headaches, depression or cancer, and other symptoms (language problems, personality changes, or impaired abilities) (Test and diagnosis, 2009). Next, doctor pass on do a physical examination, including a neurological exam to hold back reflexes, sensory function, balance, or the physiological aspects of the brain and the nervous system (Test and diagnosis, 2009). Then, doctor will do a cognitive exam, testing patients thinking, judgment, short- and long-term memory. Finally, doctor will verify any internal damage of the brain by MRI, CT scans, and electroencephalogram (Nordqvist, 2009).So far, there is not any medication or drug for the restoration of memory for patients with amnesia. Fortunately in the majority of cases, amnesia is dissipated itself without any treatment. However, if an essential physical or mental disorder is present, a treatment must be developed. Occupational healer may help patients to learn new information to replace what was lost, or using the existing memories to create new ones (Treatments and drugs, 2009). Reality orientation back up may help patients to remember if he is surrounded with familiar objects, photographs, smells, and music. If patients are suffering the Wernike-Korsakoffs amnesia, an adequate nutrition can help. Whole grain cereals, legumes, nuts, fly the coop pork, and yeast are rich sources of thiamin (Nordqvist, 2009).CONCLUSIONAmnesia is a disease that commonly means partial or total memory loss and/or the ability to store new memories. Sources of amnesia can be organic, such as brain injury caused by an accident, infection to brain cells, oxygen deprivation, or abuse of alcohol and drugs and functional, such as traumatic events or effects of stress. Amnesia can be classified depending on the factors how this is presented, such as Wernike-Korsakoffs, traumatic, or infantile amnesia and on the effects in the functionality of the brain, such as retrograde, anterograde, or transient global amnesia.The diagnosis of amnesia in a patient depends on a detailed medical history in order to discard other types of disease, physical and cognitive exams, and a verification of the brain if an injury is present. Amnesia is reversible by itself, but if physical or mental damage is presented, treatments like replacement of memories, reality orientation aids, or a rock-loving nutrition for Wernike-Korsakoff disease can be helpful solution to resolve amnesia in patients.
