Impact of Sexuality in Patients With Motor Neuron Disease.
Observational study in Muscle & nerve, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
introductionSexuality is a relevant yet understudied aspect in people living with motor neuron disease (MND). This study aimed to assess whether sexuality in people with MND is influenced by motor, cognitive, behavioral, or mood disturbances, and to explore whether being sexually active impacts caregiver burden.
methodsWe conducted a cross-sectional observational study involving participants with MND and their primary caregivers from three ALS multidisciplinary units in Seville, Spain. Data were collected between October 2018 and July 2021. Functional, cognitive, behavioral, and mood assessments were conducted. Sexuality was evaluated through sex-specific questionnaires. Caregiver burden was assessed using the Zarit Burden Interview.
resultsAmong 66 participants who completed the sexuality assessment, 42.9% reported sexual activity in the previous month. Of these, 70% had no sexual dysfunction, while 26.7% had moderate and 3.3% severe dysfunction. No correlation was found between sexual activity and motor function. Sexual activity was less frequent in participants with apathy (p = 0.026), depression (p = 0.021), and frontotemporal dementia (p = 0.013). Among sexually active patients, those with cognitive impairment-particularly memory dysfunction-had higher rates of orgasm difficulties (p = 0.019). No other clinical parameters were related to sexuality. Sexuality of participants with MND did not influence caregiver burden. DISCUSSION: Sexuality in MND is more associated with cognitive and mood factors than with motor disability. Addressing sexuality in clinical practice may contribute to improving quality of life and should be integrated into the multidisciplinary care of MND patients.
