I67: Other cerebrovascular diseases

The group of conditions categorized under "Other cerebrovascular diseases" primarily involve issues related to the blood vessels supplying the brain. These diseases generally occur when the brain's blood supply is obstructed or severely reduced, limiting the supply of oxygen and nutrients to the brain tissues. This can result in various health problems, from mild impairments to significant, life-threatening conditions. Common symptoms often include dizziness, balance problems, difficulty speaking, or sudden, severe headaches. In severe cases, these conditions might lead to a stroke or other serious issues. Disease progression varies with each specific cerebrovascular disease and can be influenced by various factors, such as a person's overall health, presence of other diseases, and lifestyle factors. The nervous system, specifically the brain and its functions, is primarily affected by these diseases.
