Substance Use and Intoxication conditions
Alcohol intoxicationAlcohol intoxication is a reversible condition caused by excessive ethanol consumption leading to impaired motor function, altered mental status, and characteristic laboratory findings.Alcohol use disorderAlcohol use disorder is a chronic relapsing brain disease characterized by compulsive alcohol use and withdrawal symptoms due to neuroadaptive changes.Alcohol withdrawalAlcohol withdrawal is a syndrome caused by sudden cessation of heavy alcohol use, leading to symptoms like tremors, agitation, seizures, and autonomic instability.Amphetamines intoxicationAmphetamines intoxication involves excessive stimulation of the central nervous system causing agitation, tachycardia, hypertension, hyperthermia, and possible psychosis.Amphetamines withdrawalAmphetamines withdrawal involves fatigue, depression, increased appetite, and sleep disturbances after stopping chronic amphetamine use due to neurochemical imbalances.Barbiturates intoxicationBarbiturates intoxication involves central nervous system depression caused by overdose, leading to respiratory failure, hypotension, and altered mental status.Barbiturates withdrawalBarbiturates withdrawal involves symptoms like anxiety, tremors, seizures, and delirium caused by sudden cessation of chronic barbiturate use affecting the central nervous system.Benzodiazepines intoxicationBenzodiazepines intoxication causes CNS depression through GABA-A receptor potentiation, leading to sedation, respiratory depression, and ataxia in overdose cases.Benzodiazepines withdrawalBenzodiazepines withdrawal involves symptoms like anxiety, insomnia, seizures, and tremors caused by abrupt cessation or reduction of benzodiazepine use.Caffeine intoxicationCaffeine intoxication is a condition caused by excessive caffeine intake leading to symptoms like restlessness, tachycardia, tremors, and gastrointestinal distress.Caffeine withdrawalCaffeine withdrawal is a syndrome caused by abrupt cessation of caffeine intake, leading to headache, fatigue, irritability, and difficulty concentrating.Cannabis/cannabinoids intoxicationCannabis/cannabinoids intoxication causes euphoria, impaired coordination, and tachycardia due to THC's activation of CB1 receptors in the central nervous system.Cannabis/cannabinoids withdrawalCannabis/cannabinoids withdrawal involves symptoms like irritability, anxiety, sleep disturbances, and decreased appetite after stopping prolonged cannabis use.Cocaine intoxicationCocaine intoxication causes intense sympathetic stimulation by blocking dopamine reuptake, leading to tachycardia, hypertension, and potential myocardial ischemia.Cocaine withdrawalCocaine withdrawal involves symptoms like fatigue, depression, increased appetite, and intense drug cravings after stopping cocaine use. It results from neurochemical imbalances.Delirium tremensDelirium tremens is a severe alcohol withdrawal syndrome characterized by confusion, hallucinations, autonomic instability, and seizures occurring 48-96 hours after cessation.Gambling disorderGambling disorder is a behavioral addiction characterized by persistent gambling despite negative consequences, linked to dopamine dysregulation in reward pathways.Inhalants intoxicationInhalants intoxication involves acute central nervous system depression caused by inhaling volatile substances, leading to euphoria, dizziness, and potential respiratory distress.Inhalants withdrawalInhalants withdrawal involves symptoms like irritability and tremors due to sudden cessation of volatile substance abuse affecting the central nervous system.LSD withdrawalLSD withdrawal involves psychological symptoms like anxiety and depression due to serotonergic system disruption after cessation of the hallucinogen.Lysergic acid diethylamide (LSD) intoxicationLysergic acid diethylamide (LSD) intoxication involves altered perception, hallucinations, and sympathetic overactivity caused by serotonin receptor agonism in the central nervous system.MDMA (ecstasy) intoxicationMDMA (ecstasy) intoxication involves serotonin release causing euphoria, hyperthermia, tachycardia, hypertension, and potential hyponatremia with altered mental status.MDMA withdrawalMDMA withdrawal involves symptoms like fatigue, depression, anxiety, and irritability after stopping MDMA use due to neurochemical imbalances in serotonin pathways.Nicotine intoxicationNicotine intoxication is a toxic condition caused by excessive nicotine exposure, leading to symptoms like nausea, vomiting, dizziness, tachycardia, and seizures.Nicotine withdrawalNicotine withdrawal involves symptoms like irritability, anxiety, and cravings caused by the sudden cessation of nicotine intake after dependence develops.Opioids intoxicationOpioids intoxication involves central nervous system depression caused by opioid overdose, leading to respiratory depression, miosis, decreased consciousness, and potential coma.Opioids withdrawalOpioids withdrawal involves autonomic hyperactivity and flu-like symptoms due to sudden cessation of opioid agonists, reflecting receptor adaptation and dependence.Phencyclidine (PCP) intoxicationPhencyclidine (PCP) intoxication causes dissociative anesthesia and agitation by blocking NMDA receptors, often presenting with nystagmus and psychosis.Phencyclidine (PCP) withdrawalPhencyclidine (PCP) withdrawal involves agitation, anxiety, and psychosis due to abrupt cessation after chronic use, reflecting NMDA receptor antagonism effects.Substance use disorderSubstance use disorder involves compulsive drug seeking despite harmful consequences, linked to altered brain reward pathways and impaired control over use.
