Cognitive Impairment, Depressive Symptoms, and Social Restrictions in Physically Recovered Stroke Patients
Abstract
Background and Purpose—Functional
outcome after stroke is often only evaluated using the modified Rankin
Scale, which primarily assesses activities of daily living. Stroke
patients may experience difficulties with social reintegration and
mental functions, feel isolated, and experience poor quality of life,
even after physical recovery is complete. Functional assessments based
solely on activity limitations may not be able to capture the full range
of problems experienced by stroke survivors.
Methods—Telephone
interviews were conducted 2 to 3 years poststroke to assess outcome on
multiple levels of functioning as stated in the WHO International
Classification of Functioning: body function (Montreal Cognitive
Assessment and Patient Health Questionnaire-2), activity (modified
Rankin Scale), and participation (Reintegration to Normal Living Index).
Results—Ninety-six
(68%) patients had a favorable functional outcome (modified Rankin
Scale <2). Of these, 79, 91, and 93 patients completed the Montreal
Cognitive Assessment, Reintegration to Normal Living Index, and Patient
Health Questionnaire-2, respectively. Forty-three (54%) patients were
cognitively impaired, 47 (52%) had restrictions in reintegration, and 30
(32%) endorsed symptoms of depression. There was no difference in
Montreal Cognitive Assessment or Patient Health Questionnaire-2 scores
between those who had activity limitations and those who had not.
Conclusions—More
than half of stroke patients with excellent functional recovery
measured by the modified Rankin Scale continue to have cognitive
impairment and participation restrictions, and one third of patients
continue to have depression 2 to 3 years later. Current definitions of
good functional outcome used in the majority of stroke acute trials
focus on activity limitations, but greater attention to multiple levels
of recovery is required.
