Caring for a Person With Amnestic Mild Cognitive Impairment.

While much of the literature on caregiver burden has focused on caregiving for people living with Alzheimer's disease (AD) there is little information on the experience of caring for a loved one living with amnestic Mild Cognitive Impairment (aMCI), the group most likely to convert to AD. A hermeneutic phenomenological approach was used to understand the organizing principles that give experiences of being form and meaning in the lifeworld. Study findings highlight the precarious nature of caregiver role acquisition and the heterogeneity that is present among informal care providers. Specifically, the findings suggest that the wearing of multiple situational masks is required by the carer to cope with accumulated progressive losses suffered as they continually adjust to their new and evolving carer identity. Support groups specific to the carers of those living with aMCI are needed in an effort to remove these masks and to validate this unique caregiving experience.

Testing a reality orientation program in patients with traumatic brain injury in a neurointensive care unit.

PRIMARY OBJECTIVE: The aim of this study was to examine the effect of a systematic reality orientation program (RO) introduced in a neurointensive care unit on duration of posttraumatic amnesia (PTA) and outcomes of patients with traumatic brain injury (TBI). RESEARCH DESIGN: This study used a quasiexperimental, prospective design. METHODS AND PROCEDURES: Twenty-four patients (intervention) with a significant TBI classified as moderate-to-severe injuries as measured by scores of less than 12 on the Glasgow Coma Scale underwent an RO program compared with a similar group of 38 patients (control) who received a conventional rehabilitation program. The Rancho Los Amigos Score was used to assess the cognitive level 24 hours after the end of sedation, and the Galveston Orientation and Amnesia Test was used daily to assess orientation and duration of PTA. The Glasgow Outcome Scale Extended was then used as an indicator of clinical outcome after 12 months. MAIN OUTCOMES AND RESULTS: The preliminary results indicated that patients who received the RO had a higher mean of the Glasgow Outcome Scale Extended (SD = 1.53) than those receiving the usual care (SD = 1.35) despite that the groups differed significantly (p = .01) in PTA duration. CONCLUSION: Patients with TBI may benefit from early assessment and systematic RO nursing intervention. The RO may facilitate patients with PTA to regain orientation and interact with their surroundings in the neurointensive care unit to optimize the recovery. However, further studies with focus on timing, intensity, and duration are needed to evaluate the influence of an early RO approach on PTA and outcomes in patients experiencing TBI.

Graduate nurse perceptions of caring for people with posttraumatic amnesia.

: This article reports a qualitative study of the phenomenon of posttraumatic amnesia, a common behavioral sequelae to traumatic brain injury frequently encountered by nurses on trauma wards. Specifically, it focuses on the experiences of newly registered Australian graduate nurses (N = 6) providing care for this patient cohort. An atheoretical qualitative descriptive design (Sandelowski, 2000) has been used to explore graduate nurses' experiences with posttraumatic amnesia. Themes that emerged from the transcripts were perceptions of behavior, difficulties in clinical management, safety, risk of wandering, external support, containment, and advocating for patient safety.

Memory disorders in children with central nervous system germ cell tumors.

Memory disorders in children and adolescents with brain tumors are rare, but devastating to social, academic, and vocational development. Many pediatric patients with intracranial germ cell tumors (GCTs) complain of memory difficulties. This study investigated memory across a series of GCT patients. A total of 33 GCT patients were retrospectively examined for diagnosis, imaging results, intelligence quotient, treatment variables, evidence of increased intracranial pressure at diagnosis, and memory. The incidence of amnesia in GCT patients was 55%. Memory disturbance could not be predicted by intelligence quotient, treatment, location of lesion, or hydrocephalus at diagnosis. The high incidence of memory deficits in GCT patients suggests a risk to memory in patients with GCT. Formal memory assessment should be considered in all patients with central nervous system GCTs. Specific counseling and planning to assist in adjustment and to ensure safety should be considered standard care for those with memory deficits. The nurse should be instrumental in facilitating understanding of this specific injury in the brain tumor population.

Medial temporal lobe amnesia: a case study for nursing.

Maintaining and enhancing cognitive function is a crucial but challenging intervention for patients with memory problems. Research on the medial temporal lobe (MTL) memory system has yielded much information that can guide nurses in planning, evaluating, and performing effective interventions. A patient, Mrs. N, with a diagnosis of anaplastic astrocytoma of the left medial temporal lobe provides an example. Information from research guides assessment of Mrs. N and affords development of specific patient-centered interventions to maintain function, cope, and compensate. Data have been gathered from the patient, relatives, and caregivers to compare with and augment existing research, because few nursing case studies of amnesia involving patients with left medial temporal lobe tumors are available for analysis.

The problem of arriving at a phenomenological description of memory loss.

This paper discusses a methodological difficulty that arose when uncovering the conscious experience of being nurtured as an in-patient with depression on a psychiatric ward. It considers the problem of arriving at a phenomenological description of memory loss in a patient who had undergone electroconvulsive therapy (ECT). The paper begins by describing the prevalence of depression and its significance for nurses working in in-patient settings. Examples of empirical research into memory loss in depression are used to show what researchers must set aside if they are to arrive at a phenomenological description of memory loss. The choice of a phenomenological approach to the wider study from which the methodological problem discussed here arose is then justified. The phenomena of memory is introduced to show the methodological significance of attempting to arrive at a phenomenological description of the statement made by one of the participants, a woman being treated as an in-patient for major depression. A possible description of the phenomena of memory loss based on the existential phenomenology of Sartre is offered to call into question the ability of researchers to bracket their assumptions. The significance for nurses of the wider study from which our example is taken is then described. Finally it is argued that despite the methodological difficulty described, a phenomenological perspective based on the philosophy of Husserl can point nurses in the direction of meeting the human needs of their patients.

Cognitive effects of electroconvulsive therapy: a clinical review for nurses.

Cognitive deficits are undesirable effects of electroconvulsive therapy (ECT). This article reviews the cognitive impairments associated with ECT, with an emphasis on linguistic information processing and memory dysfunction. Factors that may have an impact on the cognitive effects of ECT are discussed, along with recommendations for clinical interventions to aid in the treatment of these effects.

Transient global amnesia.

Transient global amnesia is a benign, self-limiting disorder primarily involving a disturbance of memory. It occurs in late middle and older aged adults. Patients with this syndrome do not have a history of head trauma, drug or alcohol intoxication, hypoglycemia or psychologic dysfunction. Once the episode has cleared, there are no residual deficits except amnesia for the events which occurred during the episode. This article includes a case presentation in addition to discussion of the clinical features, etiology, treatment and nursing interventions for the patient with a transient global amnesia episode.

Memory impairments: forgetfulness versus amnesia.

Two varieties of memory disorders can be distinguished--those characterized by the phenomenon of forgetfulness and those characterized by the presence of an amnesic state. Although these two conditions may appear similar, they have different anatomical correlates and functional significance. States of forgetfulness and amnesia arise from different etiologies, have different prognoses and require different therapeutic regimes. The purpose of this article is to distinguish these two varieties of memory disorders and contrast them as to anatomical features, functional differences, etiologies, prognoses and therapeutic management regimes. This should assist the neuroscience nurse to better understand relevant nursing assessment features and plan appropriate therapeutic nursing interventions for the client. Teaching protocols for families and significant others as well as clients with memory impairments should also be enhanced.
