Female sexual dysfunction associated with idiopathic cerebellar ataxia: A case report.

ABSTRACT: BACKGROUND:Cerebellar ataxia affects individuals in reproductive age. To date, few clinical cases of cerebellar ataxia and involvement of the cerebellum in sexual response were reported. We report a case of a woman that need to restore skills related for execution of sexual activity and coordination of movements during sexual intercourse. CASE PRESENTATION:We present a case of idiopathic cerebellar ataxia in a 25-year-old woman who was referred for sexual health consultation. The patient complained of sexual problems as follows: "I forgot the behaviors that I should adopt in a sexual encounter, and I know what to do only after paying attention to my movements." The history of sexual behavior indicated that this patient presented a "romantic love" model. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) reports that this condition involves anorgasmia disorder and female sexual arousal disorder. In addition, there was a loss of automatism and coordination of movements in the pelvis and lower extremities. The patient's condition improved with occupational and physical therapy combined with rehabilitation therapy based on cognitive behavioral criteria for sexual therapy. CONCLUSIONS:The case evolved from the romantic-affective model to a realistic model. The patient reported being comfortable during sexual intercourse and could explain her sexual needs to her partner. She managed to coordinate lower limb and pelvic movements, but did not reach an orgasm. Moreover, vaginal lubrication occurred with a time lag of 15-30?min after the end of sexual intercourse or masturbation.

Project description:Spinocerebellar ataxia type 6 (SCA6) is a rare disease that is characterized by cerebellar dysfunction. Patients have progressive motor coordination impairment, and postmortem brain tissue reveals degeneration of cerebellar Purkinje cells and a reduced level of cerebellar brain-derived neurotrophic factor (BDNF). However, the pathophysiological changes underlying SCA6 are not fully understood. We carried out RNA-sequencing of cerebellar vermis tissue in a mouse model of SCA6, which revealed widespread dysregulation of genes associated with the endo-lysosomal system. Since disruption to endosomes or lysosomes could contribute to cellular deficits, we examined the endo-lysosomal system in SCA6. We identified alterations in multiple endosomal compartments in the Purkinje cells of SCA6 mice. Early endosomes were enlarged, while the size of the late endosome compartment was reduced. We also found evidence for impaired trafficking of cargo to the lysosomes. As the proper functioning of the endo-lysosomal system is crucial for the sorting and trafficking of signaling molecules, we wondered whether these changes could contribute to previously identified deficits in signaling by BDNF and its receptor tropomyosin kinase B (TrkB) in SCA6. Indeed, we found that the enlarged early endosomes in SCA6 mice accumulated both BDNF and TrkB. Furthermore, TrkB recycling to the cell membrane in recycling endosomes was reduced, and the late endosome transport of BDNF for degradation was impaired. Therefore, mis-trafficking due to aberrant endo-lysosomal transport and function could contribute to SCA6 pathophysiology through alterations to BDNF-TrkB signaling, as well as mishandling of other signaling molecules. Deficits in early endosomes and BDNF localization were rescued by chronic administration of a TrkB agonist, 7,8-dihydroxyflavone, that we have previously shown restores motor coordination and cerebellar TrkB expression. The endo-lysosomal system is thus both a novel locus of pathophysiology in SCA6 and a promising therapeutic target.
