The National Organization for Drug-Induced Disorders aims to provide support, information, and novel research on the lasting effects caused by both illicit and prescribed medications.

These disorders include:

Hallucinogen Persisting Perception Disorder (HPPD)
Depersonalization and Derealization Disorder
Substance-Induced Psychosis
Other Substance-Induced Persistent Perceptual Disorders

PLEASE READ CAREFULLY: This web site is not intended to diagnose you, but instead provide support to those individuals who have already received the diagnosis of these disorders or individuals interested in learning about these conditions.

Vision Simulators

Note: These simulators are currently undergoing construction. However, we now have some of the visual simulators from hpponline up for viewing. -Matt 4/27/08

If you are experiencing persistent or intermittent perceptual disturbances and have not received a diagnosis from your clinician you must see your doctor regarding your condition as soon as possible. This web site will not help you diagnosis your own condition. Important tests that include MRIs, EEG, and eye examinations are neccessary when you first experience perceptual disturbances.

There are many other causes for persistent visuals and here are an example of possible conditions that would need to be addressed with your doctor: temporal lobe epilepsy , brain tumor, intercurrent drug use or possible toxic exposure at your work place or at your home, and migraine sufferers can have persistent or transient visual symptoms. Additionally, some disorders do not begin as a neurological disorder however can affect your brain as they develop including: SLE [Systemic Lupus Erythematosus], any type of recent head trauma, intraocular pathology (eye injuries or other possible conditions of your eye that need to be examined by an ophthalmologist). Other disorders that must be examined wouold be Multiple Sclerosis. which can lead to visual conditions such as sudden blindness or other visual artifacts

Our web site is currently under construction. The content is added as we are able to timely import accurate and updated information from our databases. Please note, many images on this site are not created to demonstrate a specific symbol but are simply stock images that we are using as place holders for the site design. We could have chosen to finish the web site prior to its publication, however we feel that our members and users should be able to view how this project is completed.

We have a significant amount of content that includes: interactive vision simulators, surveys for research projects, unpublished information from researchers and we will place much more information about HPPD and drug-induced disorders than ever before.

SECOND MANUSCRIPT PUBLISHED IN THE JOURNAL OF CLINICAL PSYCHIATRY Simeon, D., Kozin, D. S., Segal, K., & Lerch, B. (2009). Is depersonalization disorder initiated by illicit drug use any different? a survey of 394 adults. The Journal of Clinical Psychiatry,2009;70(10):1358–1364 doi:10.4088/JCP.08m04370) NODID'S RESEARCH WAS PRESENTED AT THIS YEAR'S INTERNATIONAL SOCIETY FOR THE STUDY OF TRAUMA AND DISSOCIATION'S CONFERENCE IN CHICAGO Abstract: Previous stud ies have documented that in a substantial minority of individuals with depersonalization disorder, onset is first triggered by drug ingestion. The goal of this study was to systematically compare a large sample of drug (D) versus non-drug (ND) initiated chronic depersonalization. We conducted an internet survey of 394 adults endorsing depersonalization and / or derealization as defined in the DSM-IV-TR. Sixty-four questions inquired about demographic and clinical characteristics, illness course, substance use histories, and treatment response. The Cambridge Depersonalization Scale (CDS) was administered. Compared to ND group (N = 198), the D group (N = 196) comprised of more male and younger individuals. The two most common precipitating drugs were cannabis and hallucinogens, followed by ecstasy, then ketamine. Comparison of the D and ND groups revealed similar illness course, impairment, suicidality, and limited treatment efficacy. The D group showed greater spontaneous improvement over time, statistically significant but not clinically robust. The groups did not differ in total CDS score or on the four subscale scores of unreality of self, perceptual alterations, unreality of surroundings, and temporal disintegration. Numbing was greater in the ND group only prior to controlling for age and gender The study documents the chronicity and morbidity of the depersonalization syndrome initiated by substance use, as well as the uniform phenotype of the syndrome regardless of antecedent.
