The review was registered in International Prospective Register of Systematic Reviews (PROSPERO; CRD420251008332) and reported in accordance with Preferred Reporting Items for Systematic reviews and Meta\u2010Analyses (PRISMA) 2020 guidelines. Study quality was assessed using Critical Appraisal Skills Programme (CASP) tools. Data were extracted on study design, sample characteristics, data acquisition method, and reported symptoms. Qualitative data were analyzed thematically following Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) principles, whereas quantitative findings were synthesized narratively within the same thematic framework.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Forty\u2010seven studies were included. Subjective symptoms of FDS were highly variable both within and between individuals. Across studies, six broad symptom domains were identified: sensory\/pain, arousal, emotional, consciousness\u2010related, cognitive, and motor symptoms. Sensory symptoms (particularly pain and headache), arousal\u2010related symptoms (especially hyperarousal), and emotional symptoms (especially panic and anxiety) were most frequently reported across studies. Symptoms related to altered awareness and dissociation between awareness and responsiveness were described in a smaller number of studies but were more consistently reported as differentiating FDS from epileptic seizures. In contrast, the differential diagnostic value of other subjective symptoms was limited by lack of specificity and insufficient detail regarding context, mode of onset, spread, duration and quality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Significance<\/jats:title>\n                    <jats:p>Subjective symptoms in FDS are diverse, but common themes emerge.
