Reversibility of cognitive and psychiatric impairments following surgical resection of frontotemporal meningiomas: a predictive factor analysis.
Article in BMC neurology, 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
backgroundCognitive and psychiatric impairments are common in patients with frontotemporal meningiomas. While meningiomas are often histologically benign, they can cause significant morbidity through mass effect and peritumoral edema. Compared to gliomas, the reversibility of these impairments following surgical resection is relatively under-investigated. This study aimed to evaluate postoperative neuropsychological changes and identify tumor-related factors associated with recovery in patients with frontotemporal meningiomas.
methodsWe retrospectively reviewed 29 patients who underwent surgical resection for frontotemporal meningiomas and completed both pre- and postoperative neuropsychological assessments (Neurooncologic Psychological Test [NOPT], Seoul Neuropsychological Screening Battery-II [SNSB-II], or Bundang Neuropsychological Testing Protocol-M1 [BNTP-M1]). Exploratory multivariable linear regression analysis was performed using Δ scores (postoperative minus preoperative) to identify radiologic factors associated with recovery in each domain.
resultsPostoperatively, patients demonstrated significant improvements across all tested domains: attention (P = 0.002), language (P = 0.041), memory (P < 0.001), visuospatial function (P = 0.024), executive function (P < 0.001), and psychiatric symptoms (P = 0.043). In exploratory multivariable analysis, mass effect was associated with greater improvement in attention (B = 1.33, 95% CI, 0.36 to 2.30; P = 0.009), whereas frontal lobe involvement was associated with less improvement in language function (B = -3.00, 95% CI, -5.06 to -0.94; P = 0.006). Convexity origin was associated with less improvement in Stroop test performance (B = -29.79, 95% CI, -59.48 to -0.11; P = 0.049), and frontal base origin was associated with less improvement in psychiatric symptoms (B = -14.91, 95% CI, -24.83 to -4.98; P = 0.005). Edema index was not significantly associated with executive function recovery in the final exploratory model.
conclusionsNeuropsychological impairments in patients with frontotemporal meningiomas demonstrated statistically significant postoperative improvements following surgical resection. Recovery trajectories may be associated with tumor-related factors such as mass effect and anatomical origin. These findings should be interpreted cautiously given the limited sample size and the exploratory nature of the analyses, and support further investigation of tailored rehabilitation strategies based on preoperative radiologic characteristics.
