Visual disturbances may be episodic, stress or substance-induced, or persistent. However, the episodes may last for 5 years or more and the symptomatology is disliked by patients (10). While a flashback is usually reported to be infrequent and episodic, HPPD is usually persisting and long-lasting.

HPPD I has a short-term, reversible and benign course. Although visual images may provoke unpleasant feelings, re-experiencing the first hallucinogen intoxication may not lead to significant concern, distress, and impairment in individual, familial, social, occupational, or other important areas of functioning [17,18].
Does stress worsen HPPD?
HPPD symptoms may cause anxiety. In turn, stress and anxiety may make HPPD symptoms worse.

What is HPPD and how do you treat it?
HPPD refers to when someone reexperiences visual and emotional sensations that can surface with psychedelic use after a substance is out of your system. The physical symptoms of HPPD are a type of “flashback” similar to what you might experience with post-traumatic stress disorder (PTSD), except it’s visual and not always distressing.
Is HPPD the result of current intoxication?
HPPD also is not the result of current intoxication. Many people first experience symptoms of HPPD days, weeks, even months after drug use. If you experience unexplained hallucinations, it’s important to see a doctor. Any and all hallucinogenic episodes are of concern. This is especially true if you experience these episodes frequently.
What are the different types of HPPD?
A review of research shows that symptoms of HPPD can be broken up into two main categories: Type I and Type II HPPD. This type of HPPD might include random, brief, and mild visual distortions that could be noticeable but cause little emotional distress.
How do I get an HPPD diagnosis?
If a psychiatric evaluation does not fit with other more common diagnoses, HPPD may be the resulting diagnosis. Reaching an HPPD diagnosis may be easier if your doctor is familiar with the condition and your past drug use. Your doctor will want to know your personal health history, as well as a detailed account of what you’ve experienced.
