Our results clearly display the common and different clinical data of CSDH in all age ranges, which is crucial to improve the management and treatment of patients with CSDH.

A total of 1118 CSDH patients were included. We found that 64.5% patients had arachnoid cyst/ventriculoperitoneal shunt in patients ≤40 years, 4.3% in the 41-79 years group, and 3.2% in the ≥80 years group (P <  0.001). Headache was the most frequent symptom in the ≤40 years group (88.2%) and the 41-79 years group (60.9%), while the most frequent symptom in the ≥ 80 years group was limb weakness (80.4%). The history of head trauma was not significantly different between the three groups. After burr hole drainage craniostomy, the disappearance or alleviation of symptoms, duration of catheter drainage, and length of hospital stay were not significantly different, while the recurrence rate was also not significantly different between the three groups. Post-operation complications are an independent risk factor contributing to the death of patients of 41-79 years (P < 0.001, B = 3.140, Exp (B) = 23.103, 95% CI = 5.142-103.809) and of ≥ 80 years (P =  0.001, B=2.831, Exp (B) = 16.970, 95% CI = 3.365-85.567). The history of antithrombotic drug was an independent risk factor of complications in patients of 41-79 years (P = 0.042, B =1.341, Exp (B) =3.823, 95% CI = 1.048-13.942) and patients of ≥ 80 years (P =  0.026, B=1.399, Exp (B) = 4.052, 95% CI = 1.178-13.933), while complications were also an independent risk factor contributing to the outcome in patients of 41-79 years (P <  0.001, B =2.254, Exp (B) =0.314, 95% CI = 0.089-1.103) and patients of ≥ 80 years (P =  0.006, B=2.074, Exp (B) = 7.953, 95% CI = 1.791-35.313). In the ≤40 years group, all patients had a good outcome (MRS score 0-3), while 98.2% (851/867) of the cases in the 41-79 years group and 94.3% (149/158) of the cases in the ≥ 80 years group saw a good outcome (P =  0.001).
