Background: The United States Food and Drug Administration approved 6 atypical antipsychotics for pediatric treatment of schizophrenia. However, little has been published on the effectiveness of these medications in the acute treatment setting of adolescents with psychosis. Since the clinical uncertainty and poor prognosis proceeding the early onset of schizophrenia has a significant impact on a child's development, there is a critical need for evidence-based data on this population.

Neuroleptic malignant syndrome (NMS), a potentially life-threatening neurological emergency characterized by muscle rigidity, altered mental status (AMS), autonomic instability, and hyperthermia, is most commonly precipitated by high-potency first-generation antipsychotics due to central dopamine receptor blockade. There is a heightened risk of NMS in animals with ischemic brain injury (IBI) or traumatic brain injury (TBI) due to the resulting death of dopaminergic neurons from injury and the dopamine receptor blockade elicited upon recovery. To the best of our knowledge, this will be the first documented case of a critically ill patient, with a history of prior exposure to antipsychotics, who suffered an anoxic brain injury with subsequent development of NMS after the initiation of haloperidol for the treatment of acute agitation.

Introduction: Charles Bonnet Syndrome (CBS) refers to visual hallucinations in visually impaired patients without psychiatric illness who are typically aware that their hallucinations are not real. Rare cases in the literature describe patients with atypical CBS, or CBS plus, who experience hallucinations in the context of sensory deficits but do not meet all of the criteria of a CBS diagnosis. These cases may include hallucinations in more than one sensory modality, including auditory hallucinations, which are thought to arise by a similar pathophysiology to that of the visual hallucinations in CBS.

Traumatic brain injury (TBI) is a leading cause of long-term disability and mortality in young adults. The devastating effects of TBI on emotion regulation, executive functioning, and cognition have been well-established, and recent research links TBI as a risk factor for neurodegenerative diseases such as Alzheimer's disease. Despite an increased focus on the long-term cognitive dysfunction associated with TBI, research into potential treatments has not yet generated consistent successful results in human subjects.

Description Neurocysticercosis, a parasitic infection of the central nervous system (CNS) caused by the Taenia solium cestode, presents clinically with a large and diverse spectrum of symptomatology, dependent upon lesion number, locale and ensuing inflammatory response. To this date, there are only two documented cases of psychosis presenting in patients with neurocysticercosis, both of which were published in India. This case presentation depicts the first documented case of Psychotic Disorder Due to Another Medical Condition: Neurocysticercosis in the United States.

Alcohol use disorder (AUD), a chronic condition that affects many people worldwide, is characterized most commonly by a preoccupation with alcohol, an irresistible craving for or the inability to control the consumption of alcohol, and the marked resultant disturbance it bestows upon one's life. Although a difficult and time-consuming condition to attempt to treat, there are currently three FDA-approved medications for AUD, including naltrexone, acamprosate, and disulfiram. However, literature points towards another agent, gabapentin, that may be efficacious in preventing relapse symptoms and cravings with enhanced effectivity in reducing post-hospitalization alcohol consumption behaviors.
