Objective: Clinical and radiological findings on neurosyphilis are fairly non-specific and there is a paucity of functional neuroimaging studies on neurosyphilis other than case reports and case series. The purpose of this study was to investigate brain perfusion abnormalities in patients with neurosyphilis.Methods: Four HIV-negative neurosyphilis patients and 4 healthy controls underwent clinical evaluation, brain technetium-99m ethyl cysteinate dimer (99mTc-ECD) single-photon emission computed tomography (SPECT) imaging, and neuropsychological assessments which included the Mini-Mental State Examination (MMSE), Clinical Dementia Rating (CDR), Clinical Dementia Rating—Sum of Boxes (CDR-SOB), and Global Deterioration Scale (GDS). Voxel-wise differences in regional cerebral blood flow were compared between the two groups.Results: Neuropsychological test results indicated cognitive impairment in all patients. SPECT analysis revealed multifocal hypoperfusion predominantly in the frontal, insular, and posterior cingulate regions in neurosyphilis patients compared with healthy controls (family-wise error corrected p < 0.05).Conclusions: Together with previous findings, our results suggest that the hypoperfusion in the frontal, insular, and posterior cingulate regions may reflect cognitive impairments observed in neurosyphilis patients. Further studies with larger samples are needed to confirm our findings.

Before And After

Akathisia, which characterized by subjective restlessness and objective hyperactivity, is induced mostly by antipsychotics and antidepressants. Chronic akathisia is defined as persistence of symptoms for more than 3 months. The pathophysiology of chronic akathisia remains unclear. This report describes a depressed patient, a 66-year-old woman with a diagnosis of major depressive disorder, with chronic akathisia. Her regional cerebral blood flow (rCBF) was measured using single photon emission computed tomography (SPECT) before and after the treatment with electroconvulsive therapy (ECT). She had experienced akathisia-like symptoms three times prior because of risperidone, escitalopram, and clomipramine administration, accompanied by major depression. After levomepromazine was added to quetiapine to treat insomnia, she developed akathisia symptoms such as a sense of restlessness and inability to sit in one place for a few minutes. These antipsychotics were withdrawn. Propranolol was administered, leading to no apparent improvement for 8 months. After she was diagnosed as having major depressive disorder and chronic akathisia, she received 10 sessions of bilateral ECT. Her depressive symptoms improved greatly. Akathisia disappeared completely after ECT. SPECT revealed that rCBF was decreased in the middle frontal gyrus and parietal lobe, that it was increased in the thalamus, fusiform gyrus, and cerebellum before ECT, and that these abnormalities in rCBF were approaching normal levels after ECT. Findings presented in this report suggest ECT as a beneficial treatment for chronic akathisia. Altered rCBF in the middle frontal gyrus, parietal lobe, thalamus, fusiform gyrus, and cerebellum, and especially decreased rCBF in the parietal lobe, may be related to the pathophysiology of chronic akathisia.
