TL;DR

PD patients with SRI frequently have behavioral features of RBD, and treatment with appropriate pharmacologic agents, such as clonazepam, may prevent future occurrences of SRI.

Abstract

OBJECTIVE: To determine the occurrence of REM sleep behavior disorder (RBD) and sleep-related injury (SRI) in an outpatient PD practice. BACKGROUND: RBD is a frequent cause of SRI in older individuals. Although RBD is seen in PD, the association of SRI and RBD in PD has not been previously assessed. DESIGN/METHODS: Consecutive patients with PD and their caregivers were interviewed using a structured questionnaire assessing the presence of RBD and SRI. Patients fulfilling the International Classification of Sleep Disorders (ICSD) criteria for RBD were compared with non-RBD patients. In a separate analysis, patients with a prior SRI were compared to those without. RESULTS: Of the 61 patient/caregiver pairs, 15% (7 men and 2 women) met the clinical criteria for RBD. There were more episodes of SRI in the RBD group, with 33% causing injury to themselves or to their caregivers compared with 6% of the non-RBD group (chi(2) = 13, p = 0.005). In the second analysis, 15% (all men) patient/caregiver pairs reported SRI. Of these, 66% of the patients had behaviors resembling those seen in RBD, and 33% had recalled dream content. There is a significant association between SRI and RBD for dream-enacting sleep behaviors (Fisher's exact test, p = 0.0001). CONCLUSION: PD patients with SRI frequently have behavioral features of RBD. If RBD underlies most SRI, treatment with appropriate pharmacologic agents, such as clonazepam, may prevent future occurrences of SRI.

These REM sleep neurobehavioral disorders constitute another category of parasomnia, replicate findings from 21 years ago in cats receiving pontine tegmental lesions, and offer additional perspectives on human behavior, neurophysiology, pharmacology, and dream phenomenology.

It is concluded that inhibitory systems were damaged by these lesions and that PS without atonia is not simply a state during which neural activity of normal PS can be expressed behaviorally.

Thermography is not helpful in the diagnosis of carpal tunnel syndrome and ulnar neuropathy because it did not reliably identify the side of lesion or distinguish between median or ulnar nerve involvement.

Fosphenytoin sodium has fewer local adverse effects after IM or IV administration than parenteral phenytoin, and systemic effects related to the CNS are similar for both preparations, but transient paresthesias are more common with fospheny toin.
