“…Limited electrophysiological studies using event-related potentials (ERPs) have been done in cluster headache patients to try and understand some of the reported higher brain abnormalities. For example, Evers et al [9] found a latency increase of P300 in cluster headache patients during the cluster period in a visual ERP test. As P300 latency is an indicator of cognitive performance [10], the authors concluded that cognitive processing is impaired during the cluster period reinforcing the possibility that cluster headache has a central origin.…”

Mid-latency and long-latency auditory evoked responses were investigated in 27 patients with cluster headache who had a mean age of 38.7+/-9.7 years and who were free of pain at the time of testing. Twenty-five age-matched healthy persons served as controls. Latencies and amplitudes of corresponding responses (N100, P200, and P300) were measured. The parameters were calculated at Pz for the P300 and Cz electrodes for the N100 and P200. Multiple analysis of variance revealed a significant overall effect of group (P=0.011). P200 amplitude was significantly smaller in cluster headache patients (P=0.0002). No differences were found for N100 or P300. These data suggest a hitherto unrecognized defect in the information processing pathways, in the early attentive phase represented by the P200 component.

Cluster headache (CH) is a neurovascular headache disease characterized by recurrent, strictly unilateral, severe pain attacks. Despite its typical clinical features, including circadian rhythm of the attacks and ipsilateral autonomic dysfunction, the underlying pathophysiology of CH is still unclear. Electrophysiological data point to central disinhibition of the trigeminal nociceptive system as one of the key mechanisms of CH pain. Therefore, altered habituation pattern and changes within trigeminal-facial neuronal circuits due to central sensitization seem to be involved. One biochemical correlate is probably represented in dysfunctions of serotonergic raphe nuclei-hypothalamic pathways. Structural and functional imaging data show an alteration of hypothalamic structures in CH patients, supporting the hypothesis that the hypothalamus, according to its function as a circadian pacemaker, plays a pivotal role in CH pathology. Cortical and brainstem reflexes are reviewed to illuminate the pathophysiology of CH.

“…Presumably, it is the unrelieved pain of CH that predisposes the sufferer to aggressive or suicidal behavior, but it also is possible that impaired cognitive processing, which is shown to be present throughout the cluster period, not just during individual headache attacks, also plays a role [27]. In any event, the consequences of such behavior may be blamed on the physician, particularly if diagnosis has been delayed or inappropriate treatment has been rendered.…”

This paper identifies legal issues of relevance to the diagnosis and treatment of cluster headache, including areas of actual and potential malpractice liability. Legal topics that are relevant to cluster headache can be divided into five categories: diagnostic-related issues, risks inherent in the disease process, prescribing and treatment-related problems, research-related issues, and disability determination.
