The study's results will inform changes to the Diagnostic and Statistical Manual of Mental Disorders-IV.
A recent study by the National Institute of Mental Health found that bipolar disorder exacts twice as much toll on workplace productivity as major depression, costing nearly half as much in lost wages. The researchers attribute this disparity to bipolar disorder's more severe depressive episodes rather than its manic periods.
Researchers find that chronic stress can lead to damage in the brain and body, but also note that certain behaviors like exercise, social support, and coping techniques can modify these effects. Healthy centenarians exhibit slower insulin rates, higher thyroid hormones, and lower cortisol levels compared to younger adults.

A study by the American Academy of Periodontology reveals that chronic stress, depression, and elevated cortisol levels are potential risk indicators for periodontal disease in adults aged 50 and older. Short-term psychological stress was linked to elevated plaque levels, while long-term physical stress was associated with gingivitis.
A study found that individuals with alcohol dependence without PTSD exhibit a disconnect between emotional distress and biological stress response to stress tests. They are more likely to relapse during the follow-up period due to this disruption.
Researchers found five predictors associated with bipolar disorder risk: people were unfriendly, co-morbid anxiety, depression diagnosis within five years, family history of bipolar disorder, and legal problems. These findings may help physicians better assess a patient's risk for bipolar disorder.
Scientists studying social stress in Syrian hamsters found that subordinates eat more and gain weight after being defeated by a dominant hamster. This model can help researchers understand human stress-induced obesity.

Probiotics offer a promising approach to managing intestinal problems caused by chronic stress.
A recent study found that 33 women (10%) experience symptoms of anxiety and stress after giving birth, independent of postnatal depression. Health practitioners should assess new mothers for broader signs of distress than depression alone to provide adequate care.
The study found that US military veterans who served in Iraq had a higher prevalence rate of mental health problems and combat experiences compared to those who served in Afghanistan or other locations. Iraq veterans used inpatient and outpatient mental health services at higher rates, with an annualized rate of utilization of 35%.
A new study found that effective methadone doses vary widely among patients, with some achieving abstinence on as little as 1.5 mg and others requiring up to 191.2 mg. Patients with posttraumatic stress disorder, depression, or a history of previous detoxifications from heroin tend to require higher doses.
Researchers at Yale discovered that brain changes associated with bipolar disorder are diminished in patients taking mood-stabilizing medications, holding promise for halting the progression of the disorder. The study's findings highlight the importance of research on bipolar disorder in youths, who are at high risk for suicide.
Researchers at Children's Hospital of Philadelphia found that parents of children with cancer often suffer from post-traumatic stress symptoms, including intrusive thoughts, avoidance behaviors, and heightened arousal. The studies suggest that these symptoms can be just as severe as those experienced by patients themselves.
Researchers found that CBZ-ERC significantly reduced manic and mixed symptoms for patients with Bipolar I Disorder. The study also showed that the medication was generally well-tolerated, with only 14.3% of patients experiencing a relapse.

Researchers found that consuming sugar snacks reduces glucocorticoid levels in rats, which can help alleviate physical and psychological stress. The study suggests that sweets made from natural sugar may be a healthy 'self-medication' option for managing stress.
Research finds that individuals with a family history of alcoholism exhibit a dysfunctional stress response prior to developing alcohol dependence, while those without a family history experience a decline after developing alcohol dependence. Low-dose alcohol consumption blocks the response to stress in both high- and low-risk groups.
The article discusses invisible disabilities such as chronic pain, depression, and posttraumatic stress disorder. These conditions often go unrecognized or underdiagnosed due to the stigma associated with disability, leading to a lack of support and acceptance for individuals who may be struggling.
Researchers found that traumatic stress can occur in children and their parents after a crash, even if no child was injured. Clinicians are recommended to screen all children involved in crashes and their parents for acute stress symptoms.

The study, which analyzed data from nearly 40,000 patients, suggests that cardiologists and internists should monitor patients with panic disorder to reduce the risk of cardiovascular disease.
Interpersonal and Social Rhythm Therapy (IPSRT) has been found to be an effective treatment for bipolar disorder, helping patients manage daily routines and relationships to prevent mania and depression. The study suggests that IPSRT is particularly beneficial for individuals with more regular social routines and better physical health.
