Hyperthymesia is also known as highly superior autobiographical memory (HSAM). According to a 2017 study, people with hyperthymesia can accurately and readily recall numerous details about events that have occurred in their life. These details can include exact dates and intricate information about previous experiences. Current research suggests that the ability is limited to autobiographical memory. This limitation means that people can only recall information about themselves and their past personal experiences. The causes of HSAM are currently unknown, but some theories suggest that it may have biological, genetic, or psychological origins. There is currently no way to diagnose hyperthymesia formally. Possible ways to assess this may be through MRI scans and complex memory tests. Hyperthymesia differs from eidetic memory in that it focuses on a person’s ability to recall their autobiographical experiences rather than to hold visualizations in their mind. Further research is necessary to examine the differences and similarities between hyperthymesia and eidetic memory.

Cold sores, also known as oral herpes, are small, painful blisters that develop around the mouth. Sometimes, people who develop cold sores will also develop a fever, which is why some people call cold sores fever blisters. They are caused by the herpes simplex virus (HSV). A cold sore is not the same as a canker sore. A canker sore is a small, painful bump that always occurs inside the mouth and is not contagious. It takes 1-2 weeks for cold sores to heal completely. However, according to Harvard Health Publishing, the virus that causes cold sores remains in the person’s body throughout their life. HSV may lie dormant for years and cause no symptoms. In some people, the virus will reactivate and cause cold sores. Between 5-10% who get cold sores get them as frequently as five times a year. Many people contract HSV as children and carry the virus throughout their life. Cold sores may return throughout an individual life, although they can become less severe over time. In most cases, home care and OTC remedies can relieve symptoms and speed healing. Prescription antiviral medications and laser treatment can also help.
