This study compare general anesthesia versus locoregional anesthesia for evacuation of chronic subdural hematoma. Half of participant will be operated under general anesthesia, while the other half will be operated under locoregional anesthesia.
General anesthesia is the most common technique for this surgery. The local anesthesia is less common but it allows to obtain the same surgical result. This last technique being more recent little study compared these two techniques in terms of complications and postoperative consequences.
The investigators will randomize patients into two groups (a general anesthesia group and a locoregional anesthesia group).
General anesthesia provides complete immobility and optimal surgical comfort but is a source of multiple complications, especially in a population of polypathological and polymedicated elderly patients (which is the population affected by chronic subdural hematomas).
Locoregional anesthesia requires special technical training, leads to complete analgesia of the surgical procedure but does not involve complete immobility of the patient, however this technique probably leads to less postoperative complications and allows a more early rehabilitation.

| LIKERT scale: a measure of the degree of satisfaction of the surgeon and the patient. | A Likert scale is a psychometric scale commonly involved in research that employs questionnaires. The format of a typical five-level Likert item, for example, could be:
| baseline |
| MINI COG: Measurement of postoperative cognitive impairment at 6 months | Two components, a 3-item recall test for memory and a simply scored clock drawing test. The test is done just before surgery, in the recovery room and the day after. | 2 days |
| Mortality rate at 6 months. | Rate of patients died 6 months after the surgery | 6 month |
| Simple numeric scale for postoperative pain | The Numeric Pain Rating Scale (NPRS) is a unidimensional measure of pain intensity in adults. The NPRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. | 2 days |
