237:- 1.1: The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life. A person with dementia may also experience changes in their mood or behaviour. 1.2: The Key functions of the brain affected by dementia are: * Language * Memory * Perception * Emotional behaviour or personality * Cognitive skills (such as calculation, abstract thinking, or judgement). 1.3: Depression, delirium and age related memory impairment could be mistaken for dementia as they all manifest with similar symptoms.
INTRODUCTION While cerebral palsy is a blanket term commonly referred to as “CP” and described by loss or impairment of motor function, cerebral palsy is actually caused by brain damage. The brain damage is caused by brain injury or abnormal development of the brain that occurs while a child’s brain is still developing — before birth, during birth, or immediately after birth. Cerebral palsy affects body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance. It can also impact fine motor skills, gross motor skills and oral motor functioning. Those with cerebral palsy were most likely born with the condition; although some acquire it later.
Alzheimer's disease affects the brain through exponentially greater cell death and tissue loss, resulting in a decreased brain size. As a result, behavior, memory and thinking are affected. Vascular dementia is caused by blockages and breaches in the brain's blood supply that damage the brain and can be caused by any condition which results in an interruption to the blood flow to the brain, and as well as strokes, this could include diseased arteries, heart attacks, high blood pressure, raised cholesterol, diabetes, furred arteries and irregular heart rhythms. Any condition causing damage to the circulation of blood to the brain carries a risk to mental functioning. People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving.
It also may due to a hemorrhage. - When the clot is block or impaired of the blood flow, it will depriving the brain from essential oxygen and nutrient. B. Hemorrhagic Stroke - Occured when blood vessel ruptured and causing leakage of blood in or around the brain. Basically, the term cerebrovascular accident (CVA) is used interchangeably with stroke to refer to the vascular conditions of brain. Clinically, a variety of facal deficits are possible including changes in the level of consciousness and impairments of sensory, motor, cognitive, perceptual and language functions.
It significantly affects the way a person feels and can interfere with every day life functioning. There are a variety of symptoms that affect everyone in different ways. Depression can be a reaction to a distressing situation like a loss, or stress, or can be part of an illness like Bipolar in which a person experiences extreme moods without any reason. It can be totally unrelated to any outside cause, but associated with a chemical imbalance in the brain. Hypnosis can be helpful for mild cases of depression, but anything else should be referred to an experienced Therapist or Doctor.
Amnesia is the general term for a condition in which memory either stored memories or the process of committing something to memory is disturbed or lost. Amnesia may result either from organic or neurological causes or damage to the brain through physical injury, neurological disease or the use of certain drugs. It could also come from functional or psychogenic causes such as mental disorder, post-traumatic stress or psychological defense mechanisms. Many kinds of amnesia are associated with damage to the hippocampus and related areas of the brain which are used in the encoding, storage and retrieval of memories. If there is a blockage in the pathways along which information travels during the processes of memory encoding or retrieval, or if
FINAL EXAM QUESTIONS TYPES OF AMNESIA: There are three types of amnesia; anterograde amnesia, retrograde amnesia, and infantile amnesia. Both anterograde and retrograde amnesia are the most severe types of memory loss disorders. They are caused by damage inflicted on the areas of the brain that provide the functioning of memory. Often, these brain injuries can be a result of severe concussions, traumatic events, and the abuse of alcohol, mental disorders, and disorders that occur from aging. Retrograde amnesia is defined as the loss of memory from the point of injury backwards.
It also regulates fear and pleasure responses. Damage to the cerebellum can result in dizziness, vertigo, ataxia which is an inability to coordinate voluntary muscle movements, unsteady movements and staggering gait. This can interfere with a person's ability to walk, talk, eat, and to perform other self-care tasks. Other symptoms of a damaged cerebellum include poor motor control, the overestimation or underestimation of force, the inability to engage in rapidly alternating movements, loss of balance and loss of muscle memory. Damage to the cerebellum seems to affect procedural learning such as touch typing.
Due to the tumor and his use of drugs, many brain processes and cognitive behavior were affected. The temporal lobes are involved in the primary organization of sensory input. The temporal lobes are also highly associated with memory. Which is why Greg couldn’t remember any events passed 1970. Damage to the temporal lobes caused the brain from registering any new events that had happened.
Characteristics of Successful Programs Addiction is a complex but treatable disease that affects brain function and behavior. Drugs of abuse alter the brain’s structure and function, resulting in changes that persist long after drug use has ceased. This may explain why drug abusers are at risk for relapse even after long periods of abstinence and despite the potentially devastating consequences. No single treatment is appropriate for everyone. Treatment varies depending on the type of drug and the characteristics of the patients.
