PTSD is a long-lasting mental disorder linked to past traumatic events

Trauma is a primary risk factor for substance use disorder later in life

Studies indicate 75% of people with substance use disorder have experienced at least one traumatic experience in their life. These experiences alter brain function, leading to heightened stress and emotional pain. Substances offer temporary relief, but this often results in dependency.

Prolonged Grief Disorder has certain recognizable risk factors

This official diagnosis is characterized by intense, daily symptoms of grief a year after the loss of a loved one among adults and faster—around at least six months—for kids and teens. Factors that put people at increased risk of this disorder include being single, attachment anxiety, violent or unnatural death, low education, low income, and multiple losses, among others.

About 12.5% of US adults experience a phobia in their lifetime, a diagnosis that hinges on the intense fear interfering with daily life and persisting for at least six months.

Depression is much more than sadness—and isn't fleeting

The American Psychiatric Association's DSM-5—used for defining diagnoses—says a person must be experiencing five or more symptoms of depression most of the day over at least two weeks.

Could all mental health disorders have a unifying 'p-factor'?

Some researchers have argued in the past couple decades that all mental health disorders may have a unifying dimension—a theoretical "p-factor" that is common across mental illness, but life experiences and behaviors influence if and how illness manifests.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

Why 'spacing out' or dissociating may help reduce trauma awareness

Dissociation may have developed as a defense mechanism in the brain to help navigate intense emotional or physical situations by providing out-of-body experiences that put distance between the mind and the environment. However, in about 1.1% and 1.5% percent of the general population, a severe form of this separation can produce alternate identities, or alters.

Schizophrenia symptoms often appear suddenly

Mental health is much more than the absence of mental illness

It's a state of well-being that allows individuals to cope with daily stressors, realize their abilities, learn and work effectively, and contribute to their overall community. Inextricably linked to physical health, modern science indicates that mental health is a central component of our overarching ability to function and enjoy life.

Misophonia is a neurological disorder where sounds trigger strong emotions

The resulting emotions, which can range from irritation and disgust to anxiety and fear, can be overwhelming and uncontrollable.

Fear or disgust related to clusters of holes and cracks, called trypophobia, may stem from evolutionary processes to help us avoid pathogens.

Synaptic plasticity allows neurons to communicate effectively and form memories

First proposed in 1949, synaptic plasticity allows the brain to adjust communication strength between neurons. This ability to change synaptic strength—either briefly or over long periods—is essential for learning and memory, with long-term synaptic plasticity forming the basis of how memories are stored.
