CT Scan report of brain of my father.

Findings of CT Scan 1) Evidence of generalized cerebral atrophy in the form of dilatation of ventricular systems and prominence of cisternal and sulcal spaces. 2) Visualized parts of orbit & paranasal sinuses appear normal except bilateral maxillary and ethmoidal sinusitis. My father, 66 years old, recently had a situation of dizziness and almost faint followed by vomiting half an hour later. Instantly he was feeling like indigestion, blood sugar was normal and bp 110/70 and he got stable in hours.  He was suggested nc ct scan of brain the findings of which are mentioned above. I have attached the report too. He is a patient of hypertension, diabetes, ckd. His cbc, echo, ecg, thyroid, usg are all normal. He has no physical or cognitional symptoms. His 24 hours holter was done in 2021 and was normal. His recent ecg is normal too.   I'm scared of his ct scan findings. Please guide and grace me.
