substance-related disorder

Substance-related disorders, also known as substance use disorders (SUDs), are complex conditions characterized by uncontrolled use of a substance despite harmful consequences.

According to various sources [1][2], SUDs involve an intense focus on using a certain substance(s) such as alcohol, tobacco, or other psychoactive substances, leading to impaired ability to function in day-to-day life.

Substance-related disorders can lead to significant impairment, including health problems, disability, and failure to meet major responsibilities at work, school, or home [15]. They can also coexist with mental health conditions, referred to as co-occurring disorders [15].

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) defines substance use disorder as a condition in which the recurrent use of alcohol and/or drugs causes clinically significant impairment [14][13].

Substance-related disorders affect people of all ages, races, sexes, genders, and socioeconomic levels [3]. They can lead to large societal problems, with a higher likelihood occurring in individuals aged 18-25, men compared to women, and urban residents compared to rural residents [10].

Addiction is defined as a chronic, relapsing disorder characterized by compulsive drug seeking, continued use despite harmful consequences, and long-lasting changes in the brain's reward system [7][8].

Signs and Symptoms of Substance-Related Disorder

Substance-related disorders, also known as substance use disorders (SUD), are characterized by a pattern of pathological behaviors related to the use of a substance. The symptoms and effects of SUD vary based on the type of substance used.

Common Signs and Symptoms:

• Intoxication: This is the immediate and short-term effect of a substance in your body, which can lead to changes in behavior, mood, and physical sensations.
• Withdrawal: When a person stops using a substance after prolonged use, they may experience withdrawal symptoms, such as tremors, anxiety, or nausea.
• Physical Symptoms: Drug addiction often presents with a range of physical symptoms, including:
  • Changes in appetite or sleep patterns
  • Weight loss or gain
  • Fatigue or energy crashes
  • Nausea or vomiting
  • Seizures or convulsions (in severe cases)
• Behavioral Symptoms: SUD can lead to changes in behavior, such as:
  • Increased tolerance for the substance
  • Needing more of the substance to achieve the desired effect
  • Spending a lot of time and money on obtaining the substance
  • Neglecting responsibilities or relationships due to substance use
• Psychological Symptoms: SUD can also lead to psychological symptoms, such as:

Substance Use Disorder Diagnostic Tools

There are several diagnostic tests used to identify individuals who have or are at risk for developing substance-related disorders. Some of the most common tools include:

• Drug Abuse Screen Test (DAST-10): A 10-question test that assesses an individual's drug use and its impact on their life [1]. Scores of 8 or more may indicate a problem with drug use.
• CRAFFT: A screening tool used to identify adolescents who have substance-related problems. It covers areas such as family, friends, recreation, and health [15].
• Substance Use Disorder Diagnostic Schedule (SUDDS): A structured diagnostic schedule used in clinical and research settings to diagnose substance use disorders and guide treatment planning [13].

Other Diagnostic Tools

In addition to these specific screening tools, there are also general diagnostic criteria for substance-related disorders. The DSM-5-TR criteria, for example, provide guidelines for psychiatrists, psychologists, and other professionals to diagnose drug-related problems [7]. Blood, urine, or other lab tests may also be used to assess drug use, although they are not a diagnostic test for addiction [10].

Importance of Diagnostic Tests

Diagnostic tests for substance-related disorders are essential in identifying individuals who need treatment. According to the United States national survey, approximately 14.5 percent of individuals age 12 or over had a diagnosable SUD in the past year [3]. Early identification and intervention can significantly improve treatment outcomes.

Medications Play a Crucial Role in Treating Substance Use Disorders

Substance use disorders (SUDs) are treatable, chronic diseases that can be managed with the help of medications, counseling, and behavioral therapies. Medications used to treat SUDs are approved by the Food and Drug Administration (FDA) and are tailored to meet individual needs.

Medications Used in Treatment

• Full agonists, such as methadone, directly stimulate receptor sites in the brain, helping to manage withdrawal symptoms and cravings.
• Other medications, like buprenorphine, can help reduce withdrawal symptoms and prevent relapse.
• Medications like naltrexone can help block the effects of opioids and other substances, reducing the risk of relapse.

Combination Therapy

Medications are often used in combination with counseling and behavioral therapies to provide a "whole-patient" approach to treatment. This comprehensive approach has been shown to be highly effective in managing SUDs.

Importance of Long-term Follow-up

Long-term follow-up is essential to prevent relapse and ensure sustained recovery. Treatment programs for SUDs usually offer individual, group, or family therapy sessions, as well as a focus on understanding the nature of addiction and becoming drug-free.

Differential Diagnosis of Substance-Related Disorders

Substance-related disorders, including substance use disorders (SUDs) and substance-induced disorders, can be challenging to diagnose due to their complex interplay with various mental health conditions. A comprehensive differential diagnosis is essential to accurately identify the underlying condition.

Key Considerations:

• Comorbidities: Comorbidity is a common occurrence among adolescents with substance-related disorders (Aarons et al., 2001). This highlights the importance of considering multiple factors when making a differential diagnosis.
• Substance use as a coping mechanism: Substance use can be a way to cope with underlying mental health conditions, such as anxiety, depression, or bipolar disorder. This is particularly relevant in cases where substance use appears to be a consequence of an existing mental health issue (1).
• Differential diagnosis among psychotic disorders: Diagnosing substance-induced psychotic disorder and other psychotic disorders can be challenging, even for experienced clinicians (10).

Common Differential Diagnosis Considerations:

• Anxiety Disorders: Anxiety disorders, such as panic disorder, generalized anxiety disorder, social phobia, dysthymic disorder, major depression, bipolar mania, or primary (idiopathic) insomnia, may be comorbid with substance-related disorders (6).
• Depression or Bipolar Disorder: Substance use can be a way to cope with underlying mental health conditions like depression or bipolar disorder (1).
• ADHD and SUD: The CPT is sensitive to ADHD-related deficits, such as disinhibition, poor timing, and inattention, and is able to consistently differentiate healthy controls from patients with ADHD, SUD, or both (4).

Guidelines for Differential Diagnosis:

• DSM-5 Handbook of Differential Diagnosis: This guide provides a framework for considering patients' presenting symptoms and history to arrive at the correct diagnoses (11).
• Table 1: Differential diagnosis of acutely intoxicated patients: This table presents differential diagnosis considerations for acutely intoxicated patients, including poor hygiene and malnutrition related to chronic substance use (3).

Substance-Induced Disorders:

• Substance-induced psychotic disorder: This condition involves experiencing delusions, hallucinations, or both within one month of using or withdrawing from alcohol, illicit substances, or prescription drugs (13).
• Substance-induced bipolar and related disorders: This condition involves experiencing manic/hypomanic symptoms, depressive symptoms, or both while using or during withdrawal from a substance (13).
