My 56F mother fell down the stairs, GCS 3, on ventilator, fixed pupils. Seeking advice on her CT scan.

My mother fell down the stairs on October 24, 2026, at around 00:00 (UTC+8) and hit the back of her head. There was bleeding, and she still hasn't woken up. A CT scan was done. She is currently on a ventilator and vasopressors, her Glasgow Coma Scale score is 3, and her pupils show no reaction to light. (She drinks alcohol every day and previously took psychiatric medication. Could that affect the pupillary light reflex?) **Additional information:** Age: 56 Sex: Female Height/weight: approximately 165 cm (5'5") / 57 kg (126 lb) Smoking: Non-smoker Alcohol: Drinks alcohol every day (exact amount unknown) Medications: She previously took sleeping pills and antidepressants, but she is not taking any psychiatric medication now that she is in the ICU. I don't know the exact names. Other medical history: Unknown Current condition: Unconscious since the fall, on a ventilator and vasopressors, GCS 3, no pupillary response to light. I really want my mom to get better, and I feel so desperate. Could anyone who looks at the CT offer some advice? English is not my native language, and I am using translation, so please forgive me if anything reads awkwardly.
