A Practical Guide to the Treatment of Neurogenic Orthostatic Hypotension [PDF]

open access: yesCanadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2014
Neurogenic orthostatic hypotension (NOH) is a debilitating condition associated with many central and peripheral neurological disorders. It has a complex pathophysiology and variable clinical presentation, which makes diagnosis and treatment difficult. Neurogenic orthostatic hypotension is often confused with other disorders of orthostatic intolerance,
