Previous and current research
The pathogenesis and the treatment of RLS and PLM represent the core of our research. We deeply characterized the time structure of PLM during sleep by elaborating an automatic computer-assisted program. We demonstrated that PLM are suppressed by dopamine-agonists. We understood that D3 subtype receptors locate within the spinal cord represent the target of dopamine agonists in RLS/PLM. We analyzed the relationship between PLM, cortical EEG arousals and autonomic activation, understanding that the three oscillating systems are highly synchronized during NREM sleep but are not directly causally related each other. By studying PLM in subjects with spinal lesions we de-monstrated that the pace-maker of PLM is located within the spinal cord and is regulated by supra-spinal dopaminergic centers. We demonstrated that pregnancy is a strong transient risk factor for RLS/PLM and that iron supplementation can improve symptoms.
To establish if PLM represents a risk factor for cardiovascular diseases. To better characterize and model the infra-slow oscillations of brain, autonomic, and motor activity during sleep. To create an animal rodent model of RLS/PLM to verify the pathogenetical role of a spinal cord disinhibition. To understand the role of iron and hypoxia in triggering RLS and PLM.
