Tóm tắt

Các tác giả nhằm so sánh sự thay đổi chất xám trong cơn tâm thần phân liệt lần đầu (FES) so với thoái hóa thùy trước - thái dương (FTLD) bằng cách sử dụng các phương pháp phân tích tổng hợp được áp dụng cho các nghiên cứu hình ảnh não. Một tìm kiếm có hệ thống được tiến hành cho các nghiên cứu MRI dựa trên voxel cấu trúc đã được công bố ở những bệnh nhân bị FES hoặc FTLD. Dữ liệu được kết hợp bằng cách sử dụng ước lượng có xác suất giải phẫu (ALE) để xác định mức độ giảm chất xám và được phân tích để xác định mức độ chồng lấn trong phân bố không gian của những thay đổi ở não trong cả hai bệnh. Dữ liệu được trích xuất từ 18 nghiên cứu FES (bao gồm tổng cộng 555 bệnh nhân và 621 đối tượng so sánh) và 20 nghiên cứu về FTLD hoặc các rối loạn liên quan (bao gồm tổng cộng 311 bệnh nhân và 431 đối tượng so sánh). Sự tương đồng trong chồng lấn không gian của những thay đổi ở não trong hai rối loạn là có ý nghĩa (p = 0.001). Các thiếu hụt chất xám chung cho cả hai rối loạn bao gồm các vùng nhân đuôi hai bên, vỏ não đảo bên trái và vùng đuôi hai bên. Có sự chồng lấn đáng kể trong phân bố của những thay đổi cấu trúc não giữa cơn tâm thần phân liệt lần đầu và thoái hóa thùy trước - thái dương. Điều này có thể phản ánh các nguyên nhân chồng lấn hoặc sự dễ tổn thương chung của các vùng này với các quá trình bệnh lý nguyên nhân khác nhau trong hai rối loạn.
