Introduction[edit | edit source]
Motoric cognitive risk syndrome (MCR) is a syndrome that develops prior to dementia. The syndrome consists of a slower gait and cognitive complaints. New research is showing that gait dysfunction can be a forerunner of dementia.[1]
MCR amongst older persons is estimated to be 10% in the 60 + age group, giving this population a higher risk of future disability.
Pathology[edit | edit source]
The pathology of MCR is due to frontal lacunar infarcts, for example:
- white matter hyperintensity (WMH),
- pre-motor and pre-frontal gray matter atrophy in the pre-motor and pre-frontal cortex
- Inflammatory changes
- genetic factors.
- Cerebrovascular lesions and cardiovascular disorders amplify the pathological changes. [2]
Diagnosis[edit | edit source]
The diagnosis of MCR is an involved process comprising neuropsychological tests, biomarker assays, imaging studies, questionnaire-based evaluation, and motor function tests. [2]
Both neurological and non-neurological clinical abnormalities occur.
- Gait irregularities and accelerated functional decline (eg postural and balance dysfunction, memory loss, cognitive decline) stem from altered afferent sensory and efferent motor responses.
- Confusing visual, vestibular, and proprioceptive inputs. [2]
Management[edit | edit source]
Management of MCR is multimodal, including
- Lifestyle habits known to limit the disease progression. Similar to dementia recommendations. eg Cognitive, physical, and social activities
- Exercise
- Diet, nutritional supplements and vitamins known to support motor and cognitive improvement. eg vit D
- Symptomatic drug treatment eg anti depressants
- Psychotherapeutic counseling[2]
Physiotherapy[edit | edit source]
Motor function tests for diagnosis and as treatment outcome measures include: including walking speed, dual-task gait tests, and ambulation ability.[2]
Exercise has been to shown to have a role in preventing cognitive decline. Home-based exercises with telephonic coaching are both safe as well as feasible in patients with Motoric Cognitive Risk syndrome[3]
