“…This flaw does not rest only with the physician as Dash et al also noted that semiological features of motor activities had the maximum yield from the witness [ 39 ]. It is expected that the motor manifestation of a seizure is what the informant focuses on as it is the most obvious, dramatic, and worrying feature of a seizure.…”

“…The suboptimal accuracy of the routine seizure history has been reported by various authors [ 23 , 42 , 43 ] though none compared the accuracy of routine description to the questionnaire. Heo et al [ 25 ], Dash et al [ 39 ], and Seneviratne et al [ 44 ] reported falsely elevated prevalence for generalized seizure using the routine clinical history. A finding that was not surprising in this study group as nonmotor focal seizures is poorly characterized in the routine seizure history.…”

Background. Burden of epilepsy in sub-Saharan Africa is huge in the midst of shortage of human resource in its health sector. Using skilled staff to supervise and support lower level healthcare workers providing frontline primary healthcare is a pragmatic coping solution. But, lower level health providers face enormous challenges due to absent clinical algorithms or pragmatic rapid diagnostic tests. Objective. This study aimed to determine if the use of an epilepsy questionnaire in a traditional clinical setting would improve semiological details obtained and diagnostic accuracy. Methods. A prospective study was conducted involving patients diagnosed with epilepsy each with an eye witness who had regularly witnessed the seizures. Routine seizure history from clinical documentation and an interviewer-based questionnaire were compared. The data obtained were assessed for content, accuracy, intermethod and test-retest reliability. Results. Sixty-seven patients with a median age of 24 years were recruited. Routine seizure history had obtained less semiological details with inadequate description of nonmotor manifestations and lateralizing motor details. The questionnaire-obtained history showed higher accuracy for generalized onset seizure (0.83 vs. 0.56) and focal onset seizures (0.79 vs. 0.59). The questionnaire-obtained history also had good test-retest reliability for various semiological domains except automatisms. Conclusions. Routine seizure histories are not standardized. The use of a questionnaire goes a long way in improving semiology description in a low-resource setting and guides the health provider on what details to focus on. The use of epilepsy questionnaires should, therefore, be considered to improve semiology, especially in nonspecialist settings.

“…The home videos submitted on follow-up visits were assessed for quality according to the Quality of Video (QOV) scale. [5] The QOV scale has 11 items, each of which was given points ranging from −1 to 2. All subjects whose home videos had QOV scores in the`fair' (QOV 5-7) or 'good'(QOV 8-10) range, were included in the study after providing informed consent, and given dates for VEEG monitoring within a month of enrolment, irrespective of the initial clinical diagnosis.…”

“…A study from our Institute showed that features in the semiology of seizures during VEEG evaluation matched better with the features observed in home videos than with those elicited from clinical history [5]. Wasserman et al showed videos of events confirmed on VEEG as PNES to various medical personnel to assess their ability to correctly recognize them; epileptologists diagnosed 87.5% of cases correctly, and general neurologists, 72.8% [1].…”

A B S T R A C TPurpose: To assess the contribution home-videos made on mobile phones can make to the diagnosis of Psychogenic Nonepileptic Seizures (PNES). Methods: Consecutive patients 10-50 years old, with episodes of altered behavior or abnormal movements, unresponsiveness, or falls, were recruited after they had obtained 'good' or 'fair' quality (quality of video scale (QOV)) home-videos of their episodes on personal mobile phones; these subjects underwent video-electroencephalography (VEEG). Diagnoses of PNES, other physiological events or epileptic seizure (ES) on homevideos (by the epilepsy fellow, step 1) and on VEEGs (by a fully trained epileptologist unaware of the home-video recording, step 2) were compared. Results: We screened 783 patients, and finally analyzed 269; 155 subjects had`fair' (QOV 5-7) and 114 had 'good'(QOV 8-10) quality home-videos. Concordance between steps 1 and 2 was seen in 261 of 269 (97.2%) subjects, and no significant difference was noted between the two modalities in diagnosing PNES. Differentiation between PNES, ES and other physiological events using home-videos was correct in 49.1% subjects if 532 (all subjects asked to make home-videos) and 70.7% if 369 (subjects with 'good' or 'fair' home videos), were used as denominators. Home-videos diagnosed PNES with the sensitivity of 95.4% (95% CI: 87.2%-99.1%), specificity of 97.5% (95% CI: 94.3%-99.2%), positive and negative predictive values of 92.65% (95% CI: 84.1%-96.8%) and 98.5% (95% CI: 95.6%-99.5%) respectively. Conclusion: Home-videos of good quality can complement VEEG in diagnosing PNES in a cost-effective way and help initiate appropriate management.

“…Home video recordings can capture rare episodes difficult to record with overnight video-EEG polysomnography in a sleep lab, picking up semiological features lacking in the history provided by the caregivers of the patients (Sartori et al 2008;Ramanujam et al 2018). Many authors concluded that also in a setting with limited resources, mobile phones, which are easy to use and not technologically challenging, can be harnessed to capture motor episodes to diagnose them accurately (Dash et al 2016).…”

Disorders of Arousal in adults: new diagnostic tools for clinical practice

Disorders of Arousal (DOA) are mental and motor behaviors arising from NREM sleep. They comprise a spectrum of manifestations of increasing intensity from confusional arousals to sleep terrors to sleepwalking. Although DOA in childhood are usually harmless, in adulthood they are often associated with injurious or violent behaviors to the patient or others. Driving motor vehicles, suspected suicide, and even homicide or attempted homicide have been described during sleepwalking in adults. Furthermore, adult DOA need to be differentiated from other sleep disorders such as Sleep-related Hypermotor Epilepsy or REM Sleep Behavior Disorder. Although many aspects of DOA have been clarified in the last two decades there is still a lack of objective and quantitative diagnostic criteria for DOA. Recent advances in EEG analysis and in the semiological characterization of DOA motor patterns have provided a better definition of DOA diagnosis. Our article focuses on the DOA diagnostic process describing accurately the newest DOA clinical, EEG and videopolysomnographic tools in order to aid clinicians in DOA assessment.
