Overview
Other stimulant abuse with intoxication delirium (ICD-10: F15.121) represents a significant public health concern, characterized by the maladaptive pattern of stimulant misuse leading to an acute state of delirium. Stimulants, such as amphetamines and methamphetamines, enhance the release of neurotransmitters, particularly dopamine, which can result in increased alertness, energy, and euphoria. However, chronic misuse can lead to profound neuropsychiatric symptoms, including delirium, agitation, and, in severe cases, psychosis. According to the National Institute on Drug Abuse (NIDA), approximately 1.6 million people in the United States reported misusing prescription stimulants in 2021, with a notable increase in methamphetamine-related admissions to treatment centers. The clinical significance of F15.121 lies in its impact on individual health, the healthcare system, and societal safety. Patients may present with self-harm or aggression, potentially leading to emergency interventions. Furthermore, the economic burden of stimulant abuse includes healthcare costs, lost productivity, and increased criminal justice expenditures, which together can exceed billions of dollars annually. Understanding the epidemiology, prevalence, and societal impact of stimulant abuse is vital for clinicians, policymakers, and public health officials aiming to mitigate its consequences.
Causes
The etiology of Other stimulant abuse with intoxication delirium is multifactorial, encompassing genetic, environmental, and psychological components. Genetic predisposition plays a significant role, with studies indicating that individuals with a family history of substance use disorders are at an increased risk for developing stimulant abuse patterns. The underlying pathophysiology is primarily centered around the dysregulation of neurotransmitters, particularly dopamine and norepinephrine. Stimulants facilitate the release and inhibit the reuptake of these neurotransmitters, leading to increased synaptic concentrations and contributing to the euphoric effects. However, chronic use can lead to neuroadaptations, including receptor downregulation and changes in dopaminergic signaling pathways, which may predispose individuals to psychotic and delirious states. Environmental factors, such as exposure to trauma or mental health disorders (e.g., ADHD, depression), can further exacerbate the risk of stimulant misuse. Additionally, the availability and social acceptance of certain stimulant drugs can contribute to patterns of abuse in specific populations, highlighting the need for targeted intervention strategies. Understanding these mechanisms is crucial in tailoring prevention and treatment efforts to address the root causes of stimulant-related delirium.

Diagnosis
The diagnostic approach to Other stimulant abuse with intoxication delirium involves a comprehensive clinical evaluation combining patient history, clinical assessment, and objective testing. Clinicians should begin with a thorough history-taking process, focusing on the timeline of substance use, types of stimulants used, and prior episodes of intoxication or withdrawal. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides criteria for diagnosing substance use disorders, including the presence of delirium as an acute confusional state. The assessment should include an evaluation of vital signs, mental status examination, and neurological assessment to identify any acute complications. Differential diagnoses to consider include other substance-induced delirium, infections (such as encephalitis), and metabolic disturbances. Laboratory testing may involve toxicology screens to confirm the presence of stimulants, as well as other relevant tests (e.g., complete blood count, liver function tests) to rule out other causes. Clinicians should also engage in clinical decision-making that considers the patient's safety, potential for harm to themselves or others, and the need for hospitalization based on the severity of symptoms. An interdisciplinary approach may involve collaboration with mental health specialists for comprehensive management.
Prevention
Prevention strategies for Other stimulant abuse with intoxication delirium should include primary prevention efforts aimed at reducing initial use among at-risk populations. This may involve educational campaigns targeting young adults and adolescents to raise awareness about the risks associated with stimulant misuse. Secondary prevention strategies can encompass screening and early intervention for individuals presenting with risk factors or early signs of stimulant abuse. Lifestyle modifications, such as promoting healthy coping mechanisms for stress and emotional regulation, can also play a pivotal role in prevention. Monitoring strategies, including regular assessments in high-risk environments (like schools or workplaces), can help identify individuals at risk for developing substance use disorders. Public health approaches should consider community-based initiatives that provide access to mental health resources and support networks, which have been shown to reduce the incidence of stimulant misuse. Risk reduction strategies must focus on creating environments supportive of recovery, thereby empowering individuals to seek help and maintain sobriety.

Prognosis
The prognosis for individuals diagnosed with Other stimulant abuse with intoxication delirium can vary widely based on several factors, including the duration and severity of substance use, comorbid conditions, and the individual’s support system. Generally, prompt recognition and management of the delirium can lead to favorable outcomes, with many individuals achieving significant recovery if they engage in comprehensive treatment. Prognostic factors include the presence of co-occurring mental health disorders, as these can complicate recovery; individuals with untreated psychological issues may experience higher rates of relapse. Quality of life impacts can be profound, with many patients experiencing difficulties in social, occupational, and personal domains due to the consequences of stimulant abuse. Long-term considerations should address not only the physical and psychological health of the patient but also the need for social reintegration and support. Factors affecting prognosis include early intervention, family support, and sustained engagement in recovery programs. Although some individuals may struggle with recurrent episodes of use, the potential for recovery remains strong, especially with a commitment to ongoing treatment and support.
Risk Factors
Identifying risk factors for Other stimulant abuse with intoxication delirium is crucial for developing effective prevention and intervention strategies. Modifiable risk factors include access to stimulants, peer influences, and availability of mental health resources. For instance, young adults in college settings with high-stress levels or those engaging in recreational drug use are at greater risk. Non-modifiable factors encompass genetic predispositions, such as family history of substance use disorders, and co-occurring mental health conditions that predispose individuals to substance abuse. Certain populations, including individuals with ADHD or those diagnosed with mood disorders, may utilize stimulants as a form of self-medication, increasing the likelihood of abuse. Additionally, socioeconomic factors, such as poverty and lack of access to healthcare, can impact an individual's risk. Screening for stimulant use disorders should consider these risk factors, particularly in high-risk populations. Prevention opportunities may include education about the dangers of stimulant misuse and access to mental health services that address underlying psychological issues.
Symptoms
The clinical presentation of Other stimulant abuse with intoxication delirium is characterized by a spectrum of symptoms that can vary in severity and duration. Initial signs often include hyperactivity, increased talkativeness, and heightened energy levels, which may progress to more severe manifestations such as confusion, hallucinations, and disorganized thinking. A notable case involves a 28-year-old male who presented to the emergency department after an all-night binge on methamphetamine. He exhibited extreme paranoia, visual hallucinations, and a fluctuating level of consciousness, consistent with intoxication delirium. In such cases, observers may note erratic behavior, agitation, and, occasionally, violent outbursts, complicating the clinical picture. Variations in symptoms may also be observed across different populations; for instance, older adults may present with atypical symptoms, such as increased lethargy rather than hyperactivity. Severity often fluctuates, necessitating ongoing assessment and monitoring. Clinicians should be vigilant in recognizing early signs of delirium, such as disorientation and inability to focus, as these can rapidly progress to more severe delirium states requiring urgent intervention. The clinical observations during intoxication can include tachycardia, hypertension, and hyperthermia, necessitating a multi-faceted treatment approach.
Treatment
The treatment and management of Other stimulant abuse with intoxication delirium require a multifaceted, evidence-based approach tailored to the individual patient. Initial management often occurs in an acute care setting, focusing on stabilizing the patient's medical condition, ensuring safety, and addressing acute delirium symptoms. Benzodiazepines are commonly utilized to manage agitation and prevent complications, while antipsychotic medications may be indicated for severe agitation or psychotic symptoms. Once stabilized, clinicians should transition to addressing the underlying substance use disorder. Evidence-based treatment options may include behavioral therapies such as cognitive-behavioral therapy (CBT) or motivational interviewing, which can help patients develop coping strategies and reduce cravings. Additionally, contingency management, which provides incentives for maintaining sobriety, may also be effective. Multidisciplinary care is essential, involving psychologists, social workers, and addiction specialists to provide comprehensive treatment support. Monitoring protocols should include regular follow-ups to assess progress and potential relapse. Family involvement in the treatment process can enhance support and improve outcomes. Long-term management may involve referral to outpatient treatment programs or support groups, such as Alcoholics Anonymous (AA) or Narcotics Anonymous (NA), to provide ongoing recovery support and prevent relapse.
