ALZHEIMER’S DISEASE/DEMENTIA


imageAlzheimer’s disease is a slowly progressive disease that is characterized by stages of declining memory, cognitive and behavioral functioning. Approximately 5 million Americans have been diagnosed with Alzheimer’s disease, with a predicted increase to 7.7 million by 2031 It is the most common form of dementia and affects more women than men (possibly because women live longer), and the risk for and incidence of this disease is slightly higher in African Americans and Hispanics than in other populations.


Although the cause of Alzheimer’s disease is unknown, several uncontrollable risk factors are associated with the development of the disease, including age, family history/genetics, and gender. Age is one of the most important factors in the development of Alzheimer’s disease. The chance of developing Alzheimer’s doubles every 5 years in individuals older than 65 years. By the time an individual reaches the age of 85, there is a 50% chance that they will develop the disease. It can, however, rarely affect individuals younger than the age of 40.


The second risk factor is family and genetics. An individual who has a first-degree relative’a sister, brother, or parent’with Alzheimer’s is at a greater risk for developing the disease. The risk increases even more if more than one family member has the illness. The gene identified that carries the risk of Alzheimer’s disease is apolipoprotein E-e4 (APOE-e4). This form of APOE gene is one of three in the body and is responsible for the development of proteins in the blood that carry cholesterol The presence of APOE-e4 increases the risk of developing the disease however, the presence of this gene does not mean development of the disease is certain. Individuals who inherit a copy of the APOE-e4 gene are simply at increased risk for developing Alzheimer’s. If the individual inherits two copies of the gene (one from each parent), he or she has an even greater risk of developing the disease; however, again inheriting the APOE-e4 gene is not a guarantee that the individual will develop Alzheimer’s disease.


The last uncontrollable risk factor is gender. Women are at a higher risk of developing the disease because they usually live longer than men. Other potential risk factors are serious head injury, high blood pressure, poorly controlled diabetes, high cholesterol, obesity, and overall poor health during the aging process. A higher incidence of obesity, diabetes, and high cholesterol also increases a woman’s likelihood of developing Alzheimer’s.


Alzheimer’s disease is a chronic, progressive disease that affects the brain structures. Changes that occur in the brain are the development of neurofibrillary tangles, amyloid or neurotic plaques, and the loss of connection between neurons. The plaques develop initially in the areas of the brain responsible for memory and cognitive functioning. Over time the plaques develop in the cerebral cortex in the areas that control language and reasoning.


The onset of Alzheimer’s disease usually occurs between 50 and 60 years of age, but may affect people as early as age 40. In the early stage of Alzheimer’s disease, the individual may appear healthy, but experiences forgetfulness, short-term memory loss, mild impairment in judgment, and difficulty in deciphering or calculating numbers. Loss of initiative and interest, decreased ability to make judgment, and geographic disorientation are also experienced. These clinical manifestations develop over time; the initial memory deterioration is so subtle that it may not be noticed. The timeframe for the early stage is 2 to 4 years.


In the middle or moderate stage, the clinical manifestations of the disease become more pronounced. The client may experience inability to recognize close family or friends, impairment of cognitive functions, disorientation to person, place, and time, agitation, confusion, possible paranoia hallucinations, and delusions. Affected individuals may wander away from their regular environment and become lost; they may experience mood swings and exhibit aggressive behaviors. The individual’s lack of concern about personal hygiene and appearance also become more noticeable.


In the final stage, clients are unable to interact with or respond to their environment. They become bedridden and are totally dependent upon others for activities of daily living. They are unable to carry on a conversation and have no recognition of self or others. This stage lasts until the individual dies, which usually occurs about 14 years after diagnosis.


There is no cure for Alzheimer’s disease. Treatment focuses on retaining memory, cognitive and physical functioning, and slowing the progression of the disease. Drug therapy consists of four medications that have been approved by the United States Food and Drug Administration: donepezil, rivastigmine, galantamine, and memantine. These medications regulate the neurotransmitters that transmit information from neuron to neuron. They are thought to help maintain cognitive and memory functioning and may control some of the behavioral symptoms. Other medications may be used to control the symptoms of insomnia, agitation, depression, and anxiety.


This care plan focuses on the adult client with Alzheimer’s disease who has been hospitalized. However, much of the information is also applicable to clients with dementia who are receiving follow-up care in an extended care facility or home setting.

CEREBROVASCULAR ACCIDENT


imageA cerebrovascular accident (CVA, stroke, brain attack) is the result of an interruption in the blood flow in areas of the brain and is characterized by the sudden development of neurological deficits that last for at least 24 hours. These deficits range from mild symptoms such as tingling, weakness, and slight speech impairment to more severe symptoms such as hemiplegia, aphasia, dysphagia, loss of portions of the visual field, spatial-perceptual changes, altered cognitive function, and loss of consciousness. Clinical manifestations depend on factors such as the area(s) of the brain affected, the adequacy of collateral cerebral circulation, and the extensiveness of subsequent cerebral edema.


CVAs are classified according to etiology. The major classifications are ischemic and hemorrhagic. Ischemic CVAs are most frequently the result of a thrombosis (which is usually associated with atherosclerosis) or an embolus. Conditions most often associated with a hemorrhagic CVA are extreme hypertension, cerebral aneurysm, or arteriovenous malformation. Treatment after a CVA is determined by the etiology and the neurological deficits that are present.


This care plan focuses on the adult client hospitalized with signs and symptoms of a CVA. Much of the information is also applicable to clients receiving follow-up care in an extended care or rehabilitation facility or home setting. This care plan focuses on the more common problems that occur as a result of a CVA. The reader should refer to neurological texts for additional information about specific speech, motor, and sensory deficits that can occur.

ADDITIONAL NURSING DIAGNOSES
















CRANIOCEREBRAL TRAUMA/CRANIOTOMY


imageThe leading causes of craniocerebral trauma (head injury, traumatic brain injury) are motor vehicle accidents, falls, sports/recreational injuries, and assaults. Examples of skull and brain injury that can occur include skull fracture; dural tear; cerebral contusion, concussion, and laceration; diffuse axonal injury (DAI); brainstem damage; and intracranial hemorrhage. Brain damage can occur during the initial injury and as a result of subsequent cerebral damage resulting from factors such as cerebral hematoma, infection, and edema; seizure activity; and/or obstruction of the flow of cerebrospinal fluid (CSF).


A craniotomy is a surgical opening into the skull to gain access to the brain. Reasons for the surgery include removing a tumor, abscess, hematoma, bone fragments, or foreign object (e.g., bullet); controlling cerebrovascular bleeding; repairing a vascular abnormality (e.g., aneurysm, arteriovenous malformation); and improving ventricular drainage. A craniectomy (excision of a portion of the skull) is the usual method of entering the brain. If this portion of the skull is replaced (using the preserved bone or a synthetic substance), it can be done on completion of the surgery or sometime in the future after there are no longer concerns about increased intracranial pressure (ICP) and/or cerebral infection.


After craniocerebral trauma, a person may have a disturbance in consciousness ranging from a brief loss of contact with the environment to persistent coma. As the level of consciousness improves, clients often experience headache, dizziness, and alterations in thought processes. These signs and symptoms tend to subside gradually but can persist for weeks to years. Additional signs and symptoms after craniocerebral trauma vary depending on the area of the brain that has been affected. For example, tissue damage in the frontal lobe could result in loss of voluntary motor control, personality changes, and/or expressive aphasia; damage to the occipital lobe could cause visual disturbances; and damage to the temporal lobe could result in receptive aphasia and/or hearing impairment. Many of the disturbances noted above may also occur after a craniotomy.


Craniocerebral trauma is classified according to location (e.g., skull, epidural area, brainstem), effect (e.g., concussion, DAI, depressed fracture of the skull, contusion, subdural hematoma), and/or severity. The severity of trauma ranges from minor (usually a concussion with no alteration in consciousness or a loss of consciousness lasting 5 minutes or less) to severe, in which extensive contusion and/or laceration of brain tissue and possible brainstem injury occurs. Severe craniocerebral trauma usually involves a period of prolonged unconsciousness and results in permanent neurological impairments that require extensive rehabilitation and long-term care.


A craniotomy is described in relation to the approach (i.e., supratentorial, infratentorial) and the location of the pathology (e.g., temporal, occipital, parietal). The neurological deficits that can occur after the surgical procedure depend primarily on the areas of the brain that are disrupted to gain access to the desired area (e.g., speech may be impaired after a temporal approach, ataxia is expected after a cerebellar approach) and the amount and location of the brain tissue that is excised or traumatized at the site of the pathology.


This care plan focuses on the adult client hospitalized after craniocerebral trauma and/or surgery. It deals mainly with nursing and collaborative diagnoses appropriate for a client who has regained consciousness after sustaining a moderate injury or undergoing an uncomplicated craniotomy. Much of the information is also applicable to clients receiving follow-up care in an extended care or rehabilitation facility or home setting. Nursing care and discharge teaching need to be individualized according to the areas of the brain affected and the extensiveness of the tissue damage. If the client has sustained more severe craniocerebral trauma, refer also to the Care Plan on Cerebrovascular Accident.
