I67.4: Hypertensive encephalopathy
Your blood pressure is too high. The high blood pressure has damaged your brain tissue.
Many blood vessels supply oxygen to the brain. Certain factors can damage the blood vessels. These include high blood pressure, for example.
If the blood pressure suddenly goes very high, the brain may not get enough blood. Then one may feel dizzy or not be able to speak properly.
If the blood pressure is too high for a long time, the blood vessels in the brain can be permanently damaged. Then sometimes not enough blood can flow through any longer. These circulatory disorders damage the nerve cells in the brain. Various symptoms can appear over a period of time. For example, one’s memory may get worse or one might get confused more often. One sometimes has problems with moving, or in carrying out certain activities.
On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.
