Dizziness, memory loss, and unresponsiveness are considered to be cerebrovascular disease if the patient is experiencing the symptoms suddenly. Ischemic cerebrovascular disease can be seen in cerebral infarcts, mostly in the brainstem area, posterior circulation, and the corpus callosum. Patients can experience dizziness, memory loss, slowed reactions, and impaired spatial structural connections. In the case of hemorrhagic cerebrovascular disease, which can be seen in patients with cerebral hemorrhage, it can also be accompanied by headache, and the cause can be determined after CT and MRI of the head. Dizziness, memory loss, and unresponsiveness can be seen clinically in patients with degenerative diseases such as multisystem atrophy or Alzheimer’s disease, also known as dementia, if the patient is showing slow and gradual worsening. Patients can present with spatial cognitive impairment, which manifests as not being able to find their homes when they go out. In patients with multisystem atrophy, this can be accompanied by dystonia, etc. If necessary, a neurology consultation is required.
