Role of Nerve Growth Factor [NGF] and Glial Cell Line.Derived Neurotrophic Factor [GDNF] in Tic Disorders

ABSTRACT

Objectives: Tic disorders are associated with neurodevelopmental origin, changes in dopaminergic neurons, and the formation of immunoreactivity, it is thought that neurotrophic factors may be crucial in the emergence of tic disorders. In this study, we targeted to explore role of neurotrophic factors in tic disorders. The aim of this study was to investigate serum Glial Cell Line-Derived Neurotrophic Factor [GDNF] and Nerve Growth Factor [NGF] levels in patients with tic disorder and healthy controls
