1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundEpilepsy is frequently accompanied by psychiatric symptoms, including mood disturbances such as depression, irritability and euphoria. Interictal dysphoric disorder (IDD), characterised by depressive and affective symptoms, is typically managed with psychiatric treatment. However, persistent symptoms, despite adequate psychiatric intervention, may indicate an underlying epileptogenic mechanism.

aimsTo highlight the importance of recognising epileptogenic contributions to persistent psychiatric symptoms, even in patients with apparently well-controlled epilepsy.

methodWe present a case report of a Japanese woman in her 40s with well-controlled epilepsy; however, she developed enduring psychiatric symptoms. Clinical features, psychiatric treatments, neurological evaluation and therapeutic outcomes are described.

resultsThe patient experienced anxiety, depression, irritability and fear, leading to an initial diagnosis of IDD. Treatment with escitalopram and olanzapine achieved only partial symptom relief. Residual symptoms prompted further investigation, which revealed symptoms suggestive of temporal lobe epilepsy auras. Adjustment of anti-seizure therapy with lacosamide resulted in complete resolution of psychiatric symptoms, marked functional recovery and a reduction in her Hamilton Depression Rating Scale (HAMD-17) score improved from 23 to 6.

conclusionsThis case highlights that even in apparently well-controlled epilepsy persistent psychiatric symptoms may indicate an underlying epileptogenic mechanism rather than a primary psychiatric disorder. Careful evaluation and appropriate optimisation of anti-seizure medication can yield substantial psychiatric and functional improvements, underscoring the importance of multidisciplinary assessment in such presentations.
