According to Katzenschlager and Pirker walking speed is a sensitive indicator of general health status and it associated with life expectancy in older adults. Accurate pathology diagnosis is the most important among patients exhibiting neurological disorders of gait. Several studies have investigated ‘the relationships between gait impairments and activity limitations in people with’ various neurological disorders. Studies show that depression has been associated with increased risk of gait impairments. This study reviewed and ‘synthesized existing evidence on gait’ impairments in neurological disease, including Depressive, Depressive Pseudodementia, Hypochondriasis, Factitious disorder, Cognitive dysfunction and Normal Pressure Hydrocephalus. The aim of this research study is to review the various neurological factors particularly relevant to depression diseases, affecting gait impairments.
