Dopamine and serotonin: Brain chemicals explained

Dopamine and serotonin are chemical messengers, or neurotransmitters, that help regulate many bodily functions. They have roles in sleep and memory, as well as metabolism and emotional well-being.

People sometimes refer to dopamine and serotonin as the “happy hormones” due to the roles they play in regulating mood and emotion.

They are also involved in several mental health conditions, including low mood and depression.

Dopamine and serotonin are involved in similar bodily processes, but they operate differently. Imbalances of these chemicals can cause different medical conditions that require different treatments.

Adults who mix cannabis with opioids for pain report higher anxiety, depression

A researcher from the University of Houston has found that adults who take prescription opioids for severe pain are more likely to have increased anxiety, depression and substance abuse issues if they also use marijuana.

“Given the fact that cannabis potentially has analgesic properties, some people are turning to it to potentially manage their pain,” Andrew Rogers, said in describing the work published in the Journal of Addiction Medicine. Rogers focuses on the intersection of chronic pain and opioid use, and identifying the underlying psychological mechanisms, such as anxiety sensitivity, emotion regulation, pain-related anxiety, of these relationships. Rogers is a doctoral student in clinical psychology who works in the UH Anxiety and Health Research Laboratory and its Substance Use Treatment Clinic.

Under the guidance of advisor Michael Zvolensky, Hugh Roy and Lillie Cranz Cullen Distinguished University Professor of psychology and director of the lab and clinic, Rogers surveyed 450 adults throughout the United States who had experienced moderate to severe pain for more than three months. The study revealed not only elevated anxiety and depression symptoms, but also tobacco, alcohol, cocaine and sedative use among those who added the cannabis, compared with those who used opioids alone. No increased pain reduction was reported.

What is the link between sleep apnea and depression?

New research has explored the link between sleep apnea and depression and suggests that the former may be one reason that depression treatments fail.
