Responsive to levodopa treatment
Parkinsonism that is responsive to treatment with levodopa has previously been identified in certain types of SPG11 HSP. Now for the first time, it has also been identified in the case of SPG7 HSP. SPG11 HSP is associated with impairment in mechanisms of vesicular trafficking and organelle shaping, while SPG7 HSP is associated with impaired mechanisms in mitochondrial function.
We report a 55-year-old woman with a long history of a gait disturbance that was followed by dysarthria and urinary incontinence. She underwent brain MRI, SPECT with TRODAT imaging and whole-exome sequencing, revealing the diagnosis of SPG7. She developed parkinsonism responsive to levodopa, expanding the phenotype of complex SPG7.
