Memory disorders are the result of damage to neuroanatomical structures that hinders the storage, retention and recollection of memories. Memory disorders can be progressive, including Alzheimer's diseaseor they can be immediate including disorders resulting from head injury. Agnosia is the inability to recognize certain objects, persons or sounds. Agnosia is typically caused by damage to the brain most commonly in the occipital or parietal lobes or from a neurological disorder. Treatments vary depending on the location and cause of the damage.

Recovery is possible depending on the severity of the disorder and the severity of the damage to the brain. Alzheimer's disease AD is a progressive, degenerative and fatal brain disease, in which cell to cell connections in the brain are lost. Alzheimer's disease is the most common form of dementia. Amnesia is Memkry abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient. People with anterograde amnesia show difficulty in the learning and retention of information encountered after brain damage.

People with retrograde amnesia generally have memories spared about personal experiences or context independent semantic information.

Traumatic brain injury TBI often occurs from damage to the brain caused by an outside force, and may lead to cases of amnesia depending on the severity of the injury. Occasionally, post-traumatic amnesia PTA may exist without any retrograde amnesia RAbut this is often more common in cases of penetrating lesions.

Damage to the frontal or anterior temporal regions have been described Tohal be associated with disproportionate RA. Studies have illustrated that during PTA, head injury patients showed accelerated forgetting of learned information. On the other hand, after PTA, forgetting rates were normal. As noted in the above-mentioned section on traumatic brain injury it can be associated with memory impairment, Alzheimer's disease; however, as this web page as aging is concerned it poses other threats as well.

There is evidence that supports a high incidence of falls among the elderly population and this is a leading cause of TBI-associated death among the population of people 75 years of age and older. Another factor associated with TBI and age is the relationship between when the injury was sustained and the age at which it occurred.

It is estimated that the older the individual, the more likely they would require assistance post TBI. In some cases, individuals have reported having a particularly Memory Is The Sum Total Of What memory for images or sounds occurring immediately Memoyr the injury, on regaining consciousness, or during a lucid interval between the injury and the onset of PTA. As a result, recent controversy has emerged about whether severe head injury and amnesia exclude the possibility of post-traumatic stress disorder PTSD symptoms.

These 'windows' involved recall of events close to impact when RA was briefof distressing events soon after the accident when PTA was shortor of 'islands' of memory e. Brain injuries can also hWat the result of a stroke as the resulting lack of oxygen can cause damage to the location of the cerebrovascular accident CVA. The effects of a CVA in the left and right hemispheres of the brain include short-term memory impairment, and difficulty acquiring and retaining new information. Dementia refers to a large class of disorders characterized by the progressive deterioration of thinking ability and memory as the brain becomes damaged. Dementia can be categorized as reversible e. Alzheimer's disease.

In the United States alone the number of people affected by dementia is striking at 3. While mild cognitive impairment can be considered a normal part of aging, the differences must be noted. In one study by J.]
