Stroke is a common disease in the older population. Many gender differences are seen in the epidemiology, outcomes, and treatment of geriatric stroke. Although these differences are not fully understood, recognition of gender differences may help with appropriate treatment and improve outcomes.
Key words: stroke, gender, outcomes, prevention, treatment.

Depression, the most frequent neuropsychological problem after stroke, is greatly influenced by the complex relationships between the neurobiological and psychological changes that occur after stroke. Post-stroke depression leads to negative rehabilitation outcomes including less participation in therapy, extended recovery time, significantly decreased quality of life, and increased utilization of health care resources. Because of the high prevalence of post-stroke depression, all stroke survivors should be screened early in the rehabilitation process. Use of a biopsychosocial framework acknowledges the multifactorial etiology of post-stroke depression and contributes to effective, evidence-based treatment. Attention to the needs of the family caregivers further promotes successful post-stroke rehabilitation.
Key words: stroke, depression, risk factors, recovery, treatment.

Depression is a common sequela of stroke, occurring in approximately 33% of all patients. Post-stroke depression (PSD) is associated with greater cognitive and functional impairments, excess mortality, and increased health care costs, although symptoms are often mild. Diagnosis of PSD can be made using standard clinical criteria, despite the potential overlap with the somatic and vegetative symptoms of stroke. Post-stroke depression responds to standard antidepressant pharmacotherapies, but use of tricyclic antidepressants may result in increased cardiac adverse events. Given the high prevalence and major negative impact of PSD, active screening of all stroke patients for depression and aggressive treatment is recommended.
Key words: stroke, depression, diagnosis, risk factors, treatment.

Chronic Primary Insomnia among Older Individuals

Chronic Primary Insomnia among Older Individuals

Teaser: 

Børge Sivertsen, PhD, Department of Clinical Psychology, University of Bergen, Bergen, Norway.

Chronic primary insomnia is a sleep disorder with no known secondary etiology, and the prevalence increases with advancing age. Insomnia is associated with a range of adverse consequences, both on an individual and societal level. While pharmacotherapy is still the most common form of treatment of late-life insomnia, it is associated with a number of side effects, and recent evidence shows cognitive-behavioural therapy (CBT) to be more effective in managing chronic primary insomnia. This article will discuss the development, consequences, assessment and treatment of chronic primary insomnia among older adults.
Key words: sleep initiation and maintenance disorders, aged, morbidity, treatment, insomnia.

Skin Ulcers in Older Patients

Skin Ulcers in Older Patients

Teaser: 

Christopher Frank, MD, CCFP, Department of Medicine, Division of Geriatrics, Queen’s University, Kingston, ON.

Skin ulcers are common among older adults, especially those in hospital or in long-term care facilities. Prevention of ulcers is important in all clinical settings. Clarifying the cause(s) and exacerbating factors is the first step in management. Pressure and venous insufficiency are the most common causes among older adults. Poor nutrition, edema, arterial insufficiency, and anemia may impair wound healing. Adequate debridement and cleaning is important to decrease infection risk and to promote healing. The choice of dressings depends on the needs of the individual wound but should emphasize the provision of a moist wound environment. Options for dressings are summarized.
Key words: skin ulcers, treatment, wound healing, older adults, pressure ulcers.

An Update on Strategies to Prevent and Treat Delirium

An Update on Strategies to Prevent and Treat Delirium

Teaser: 


Sudeep S. Gill, MD, MSc, FRCPC, Assistant Professor, Division of Geriatric Medicine, Queen’s University, Kingston, ON.

Delirium is common among hospitalized older adults and is associated with significant morbidity and excess mortality. Despite its prevalence and consequences, delirium is often underrecognized and undertreated. Antipsychotic drugs are commonly used to manage symptoms of delirium, but few controlled trials exist to support their efficacy and safety in this setting. Several recent studies have focussed on preventing delirium in high-risk populations. Clinical trials have demonstrated benefits with multifaceted nonpharmacological interventions, but widespread implementation of these interventions has not yet occurred. Two recent drug trials evaluated an antipsychotic and a cholinesterase inhibitor to prevent delirium, but neither trial demonstrated a reduction in incident delirium. At present, the most promising approach involves targeted, multifactorial interventions that focus on preventing delirium in high-risk patient groups. More work is needed to facilitate the implementation of these evidence-based strategies.
Key words: delirium, prevention, treatment, antipsychotic drugs, cholinesterase inhibitors.

Multiple System Atrophy: An Update

Multiple System Atrophy: An Update

Multiple system atrophy (MSA) is a sporadic neurodegenerative disorder characterized clinically by various combinations of parkinsonian, autonomic, cerebellar, or pyramidal signs and pathologically by cell loss, gliosis, and a-synuclein-positive glial cytoplasmic inclusions in several brain and spinal cord structures. The clinical recognition of MSA has improved, and the recent consensus diagnostic criteria have been widely established in the research community as well as in movement disorders clinics. Although the diagnosis of this condition is largely based on clinical expertise, several investigations have been proposed in the last decade to assist in early differential diagnosis. Symptomatic therapeutic strategies are still limited.
Key words: multiple system atrophy, clinical presentation, diagnosis, treatment.

An Office Diagnosis of Mild Cognitive Impairment

Mild Cognitive Impairment (MCI) describes a state of abnormal cognitive functioning that is insufficient to warrant a diagnosis of dementia. While dementia requires that activities of daily functioning be compromised due to cognitive symptomology, the diagnosis of MCI can be made earlier, in the absence of such functional impairment. In MCI, the patient must present with cognitive complaints (or someone who knows the patient well must present them on the patient's behalf), and these complaints must be corroborated by abnormalities on standardized cognitive testing. The diagnosis of MCI alerts the clinician to a higher risk of future development of dementia and provides an ideal target population that may benefit the most from “disease-modifying” cognitive therapies currently in development.
Key words: mild cognitive impairment, MCI, Alzheimer’s disease, dementia, early diagnosis, treatment.

Diagnosis and Management of Bipolar Disorder

Bipolar disorder is less common in the older adult population. However, the quality of life for older adults with bipolar disorder is significantly impacted. Older patients with bipolar disorder have more cognitive and functional impairment than younger patients. Studies show that older adults with bipolar disorder also have an increased risk of suicide, dementia, and medical illness, as well as a higher mortality rate. This article provides a review of the epidemiology, clinical features, suicide risk, comorbidities (including dementia), and management of bipolar disorder in older adults.
Key words: bipolar disorder, mania, bipolar depression, treatment.

Nonpharmacological Management of Hypokinetic Dysarthria in Parkinson’s Disease

In addition to its widely recognized effects on gait, posture, balance, and upper limb coordination, Parkinson’s disease (PD) can have a profound effect on speech and voice, within a cluster of speech characteristics termed hypokinetic dysarthria. Although dopaminergic therapy produces significant benefits in the early stages of PD, speech symptoms may show selective resistance to pharmaceutical therapy in patients with a disease history of more than 10 years. This article discusses the pathophysiology of PD as it relates to speech disorders and considers nonpharmaceutical therapeutic options for hypokinetic dysarthria.
Key words: Parkinson’s disease, speech pathology, dysarthria, treatment.
