PTSD is a psychiatric disorder marked by a person having intense, disturbing thoughts and feelings related to a traumatic event they experienced in their past. They may relive the event through flashbacks or nightmares; they may feel sadness, fear or anger; and they may feel detached or estranged from other people. People with PTSD may avoid situations or people that remind them of the traumatic event, and they may have strong negative reactions to something as ordinary as a loud noise or an accidental touch.
Posttraumatic stress disorder (PTSD) is a psychiatric disorder that can occur in people who have experienced or witnessed a traumatic event such as a natural disaster, a serious accident, a terrorist act, war/combat, rape or other violent personal assault.
For most patients, episodes of major depression last a limited amount of time, usually lasting several weeks or months. But for some patients, the condition becomes chronic — with symptoms lasting at least two years.
The differences between episodic and chronic depression encompass more than just duration. Studies show that, compared with episodic major depression, chronic depression causes more functional impairment, increases risk of suicide, and is more likely to occur in conjunction with other psychiatric disorders.
Exact causes of chronic depression are unknown, but certain factors may contribute to the development of the condition. These include:
Substance use disorder occurs when a person's use of alcohol or another substance (drug) leads to health issues or problems at work, school, or home.
Commonly used substances include:
The exact cause of substance use disorder is not known. A person's genes, the action of the drug, peer pressure, emotional distress, anxiety, depression, and environmental stress can all be factors.
Many who develop a substance use problem have depression, attention deficit disorder, post-traumatic stress disorder, or another mental problem. A stressful or chaotic lifestyle and low self-esteem are also common.
Opioids, sometimes called narcotics, are a type of drug. They include strong prescription pain relievers, such as oxycodone, hydrocodone, fentanyl, and tramadol. The illegal drug heroin is also an opioid.
A doctor may give you a prescription opioid to reduce pain after you have had a major injury or surgery. You may get them if you have severe pain from health conditions like cancer. Some doctors prescribe them for chronic pain.
Other risks of using prescription opioids include dependence and addiction. Dependence means feeling withdrawal symptoms when not taking the drug. Addiction is a chronic brain disease that causes a person to compulsively seek out drugs, even though they cause harm. The risks of dependence and addiction are higher if you misuse the medicines. Misuse can include taking too much medicine, taking someone else's medicine, taking it in a different way than you are supposed to, or taking the medicine to get high.
After years of opiate use, many patients could become unintentionally dependent to the very medication that helps them function. This is a very complex scenario and patients need great care in navigating themselves back to health and safety. The risks of dependence and addiction are higher if you misuse the medicines. Misuse can include taking too much medicine, taking someone else's medicine, taking it in a different way than you are supposed to, or taking the medicine to get high.
