Randomized Controlled TrialAnalgesic effect of intrathecal baclofen bolus on neuropathic pain in spinal cord injury patients.
GABA-ergic neurons are widely distributed throughout the central nervous system, including the spinal cord which is important for the transmission of pain impulses to the brain. Here we hypothesized that intrathecal baclofen (ITB) which is a GABA analogue might exert analgesic effects on neuropathic pain, which could be related to subtypes of pain in spinal cord injury (SCI). ⋯ ITB has analgesic effects on all subtypes of neuropathic pain and can improve interference of neuropathic pain with activities of daily living. ITB might be a promising analgesic treatment to control neuropathic pain.

Randomized Controlled Trial Clinical TrialEffects of NMDA receptor antagonist memantine on mismatch negativity.
Mismatch negativity (MMN) and its magnetic counterpart (MMNm) have been shown to be altered in patients with various psychiatric and neurological disorders, e.g. Alzheimer's disease and schizophrenia, indicating deficits in involuntary attention. N-Methyl-D-aspartate (NMDA) receptor-mediated glutamate dysfunction is suggested to underlie these deficits. ⋯ No changes in amplitude or latency were observed for P1 and N1 peaks. These results indicate that memantine affects involuntary attention without otherwise changing auditory processing of the stimuli. As memantine-induced changes in MMN were detected only in EEG, we suggest that the effect is mostly related to the frontal cortex.
