ASZED - The African Schizophrenia EEG Dataset

ASZED (African Schizophrenia EEG Dataset) is the first publicly available EEG dataset from African indigenous populations for schizophrenia studies. The dataset contains EEG recordings from 76 schizophrenia patients and 77 healthy controls across multiple paradigms: resting state, cognitive tasks, auditory oddball (MMN), and 40Hz stimulation (ASSR). Recorded at two Nigerian sites using standardized protocols, ASZED aims to improve representation of African populations in computational psychiatric research.ASZED（非洲精神分裂症脑电图数据集，African Schizophrenia EEG Dataset）是首个面向精神分裂症研究、来自非洲原住民群体的公开可用脑电图（Electroencephalogram, EEG）数据集。该数据集收录了76名精神分裂症患者与77名健康对照个体的脑电图记录，涵盖多种实验范式：静息态（resting state）、认知任务、听觉oddball任务（失匹配负波，Mismatch Negativity, MMN）以及40Hz刺激（听觉稳态响应，Auditory Steady-State Response, ASSR）。该数据集于尼日利亚的两个采集站点采用标准化实验协议完成采集，旨在提升非洲群体在计算精神病学研究中的样本代表性。
