Ice bucket at first…and then? – Psychopathology in amyotrophic lateral sclerosis patients and their caregivers, a review

Abstract

IntroductionAmyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder that affects motor neurons in the cerebral cortex, brainstem and spinal cord. The progressive loss of motor function creates profound changes on patient's lives and their caregivers.ObjectiveAssessment of eventual existence of psychopathology in ALS patients and their caregivers.MethodsLiterature review using the terms: ALS, Amyotrophic Lateral Sclerosis, psychopathology, psychiatric disorder; depression; anxiety, caregivers.ResultsModerate depressive or anxious symptoms are often observed. The results are not consistent, some studies showing that major depression is less common that in general population, others that is mildly increased. Some studies show that depressive symptoms are related to poorer QoL and with faster disease progression, others suggests no correlations. Coping strategies, cognitive appraisal and social support are important factors to psychological adaptation to ALS. After the diagnosis, high levels of anxiety can be observed. Psychopathological features are observed at this time, and generally depression does not increase as death approaches. Beyond loss of physical functions, it seems that patients’ neurobehavioral symptoms, such as aggressiveness, disinhibition and impulsivity, cognitive impairment, and also lack of social support have a negative effect on caregivers’ mental health. Concordance between patient and caregiver distress was found.ConclusionsIt is important to assess potential psychological distress in ALS patients and their caregivers, given that cope with disease can affect its course. Caregivers’ needs should be addressed, to benefit their well-being and consequently patients’ QoL. There are few studies about psychopharmacotherapy and/or psychotherapy in these patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.
