UCLA Doctors Reportedly Believe Lindsay Lohan Was Wrongly Diagnosed. Lindsay Lohan’s previous diagnosis is incorrect, her doctors at UCLA apparently concluded. The troubled actress reportedly doesn’t suffer from drug or psychiatric problems, and is now up for a shorter rehab stay. Sources familiar with the treatment told our source that doctors determined Lohan isn’t an addict after she was “weaned off” all of her meds – Dilaudid, Ambien, Adderall, Zoloft, Trazodone and Nexium – and had no adverse reaction. She also had no withdrawal issues in the alcohol department. Lohan was apparently misdiagnosed with Attention Deficit Hyperactivity Disorder in the past, which is why she started taking Adderall, though UCLA doctors say she doesn’t have ADHD. They also believe that she is not bipolar, but she suffers from a personality disorder that is common in society and sometimes partly the result of difficulties one encounters when growing up in Hollywood. The doctors reportedly recommend the maximum amount of time she should spend there is 30 days, followed by outpatient care. Meanwhile, addiction specialist Dr. Joe Haraszti, who is not connected with Lohan’s medical case, told the website that constantly taking Adderall when it’s not needed might have a negative effect on the actress. Those who take Adderall unnecessarily can experience similar effects as those who use cocaine or methamphetamine.
