Frequent falls Neuroimaging in a patient with Progressive Supranuclear Palsy

Abstract

Falls in the elderly are common, dangerous and often disabling. They are often multifactorial and require extensive diagnostic approach. Dementia, Idiopathic Parkinson's Disease, cerebrovascular disease and neuropathies are among the most frequent neurological condictions associated with falls. However, if a patient has had early instability and recurrent falls associated with a Parkinsonian syndrome, particularly at the beginning of the disease, it should suggest the diagnosis of Progressive Supranuclear Palsy (PSP). PSP is essentially a clinical diagnosis, however, given the bleak prognosis, Magnetic Resonance Imaging (MRI) of the brain is performed in all patients to exclude alternative diagnoses and to look for supporting features of PSP. These include signal increase and atrophy of the midbrain, thinning or smudging of the substantia nigra, atrophy of the putamen, atrophy and signal increase of globus pallidus.

We present the case of an adult patient who had dementia and parkinsonism refractory to levodopa with frequent falls in whom typical findings of PSP were documented in MRI. In addition, a brief review of the main findings in Parkinsonian Dementias images and fall prevention in these patients.
