The use of steroids often raises concerns about their potential impact on mental well-being. A key question is whether these substances contribute to serious psychiatric conditions like schizophrenia. This article clarifies the relationship between steroid use and mental health, distinguishing between different types of steroids and exploring the scientific understanding of their effects on the brain. It examines if steroids directly cause schizophrenia or primarily influence individuals with existing vulnerabilities.
Different Types of Steroids
When discussing “steroids,” it is important to distinguish between two primary categories: corticosteroids and anabolic-androgenic steroids. Corticosteroids, such as prednisone, are medications prescribed for their anti-inflammatory and immunosuppressive properties. These are artificial versions of hormones like cortisol, used to treat conditions such as asthma, allergies, autoimmune diseases, and inflammatory bowel disease. They can be administered in various forms, including oral tablets, injections, inhalers, or topical creams.
In contrast, anabolic-androgenic steroids (AAS) are synthetic derivatives of testosterone. These steroids are primarily known for promoting muscle growth and enhancing athletic performance, often associated with illicit or non-medical contexts. While AAS have legitimate medical applications, such as treating hormone deficiencies or muscle-wasting conditions, their non-medical use is common among athletes and bodybuilders. They exert their effects by binding to androgen receptors, influencing protein synthesis and cell growth.
Mental Health Effects of Steroid Use
Both corticosteroids and anabolic-androgenic steroids can influence mental health, manifesting a range of psychiatric symptoms. Corticosteroids are known to induce mood changes, including irritability, euphoria, depression, and anxiety. These effects can appear within days of starting treatment and may vary in intensity. Sleep disturbances, such as insomnia, and cognitive difficulties like confusion, are also reported side effects.
Anabolic-androgenic steroids similarly impact psychological well-being. Users may experience heightened irritability, aggression, and significant mood swings, sometimes called “roid rage.” Depression and anxiety are commonly reported, both during use and particularly during withdrawal periods. These mental health changes relate to the steroids’ influence on neurotransmitter pathways in the brain.
Steroid use can lead to a temporary condition known as steroid-induced psychosis. This can involve symptoms like delusions, hallucinations, and paranoia. This condition is distinct from chronic mental illnesses like schizophrenia, as it typically resolves with a reduction in dosage or discontinuation of the steroid. The occurrence and severity of these psychiatric effects depend on the type, dosage, and duration of steroid use.
The Relationship Between Steroids and Schizophrenia
Steroids do not typically cause new-onset schizophrenia in individuals without a prior predisposition. However, these substances can trigger or worsen psychotic episodes in individuals who are vulnerable or possess a pre-existing genetic susceptibility to psychotic disorders. This distinction is important for understanding their impact on mental health.
The psychotic symptoms induced by steroids, such as hallucinations or delusions, are classified as a “Substance/Medication-Induced Psychotic Disorder,” not schizophrenia. A differentiating factor is the typical course and reversibility of steroid-induced psychosis. These episodes often resolve within days to weeks after the steroid dosage is reduced or discontinued. Schizophrenia, in contrast, is a chronic condition characterized by persistent symptoms over a prolonged period, and does not spontaneously remit upon cessation of a substance.
The mechanisms by which steroids can induce psychosis involve alterations in brain chemistry, including neurotransmitter pathways like dopamine and serotonin. While these changes can lead to psychotic symptoms, they differ from the complex neurobiological underpinnings of schizophrenia. Therefore, while steroids can induce a psychotic state that may resemble aspects of schizophrenia, the underlying cause, typical duration, and prognosis are distinct. The presence of a pre-existing vulnerability is a significant factor in determining who might experience such an adverse reaction.
Why Some People Are More Affected
Not everyone who uses steroids will experience mental health effects, and the severity varies among individuals. Several factors contribute to this difference in susceptibility. The dosage and duration of steroid use are significant; higher doses and prolonged use, particularly of corticosteroids, are more strongly associated with an increased risk of psychiatric symptoms, including psychosis.
Individual physiological sensitivity also plays a role, as people metabolize and respond to medications differently. Pre-existing mental health conditions, whether diagnosed or undiagnosed, can heighten an individual’s vulnerability. Patients with a history of mood disorders, anxiety disorders, or other psychiatric illnesses are at an elevated risk for experiencing steroid-induced mental health issues. Genetic predispositions, such as variants in genes related to dopamine, serotonin, and cortisol pathways, may also influence how an individual’s brain reacts to steroids, explaining why some are more affected than others.
