Patients with cerebral arteriosclerosis may also experience some emotional and behavioral changes. Such as reduced self-control, easily sad, sometimes depressed, sometimes happy, easily excited. Some are irritable, suspicious, panic-stricken, and indecisive. Some develop euphoria and forced giggling. The mental symptoms of early cerebral arteriosclerosis are sometimes mild and sometimes severe, and the performance varies from person to person, alternating. It is often misdiagnosed as “neurasthenia”, “neurosis” and “menopause syndrome”. Therefore, when the above-mentioned conditions occur, it is more important to be alert and diagnose early to avoid treating it as a mental illness.
