Psychosis: Goals of Pharmacotherapy01:26

Psychosis: Goals of Pharmacotherapy

101
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Drug Therapy01:28

Drug Therapy

32
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

Alzheimer's Disease: Treatment

139
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Psychosis and Antipsychotic Drugs: Overview

167
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Mania and Antimanic Drugs: Overview

106
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Management of Insomnia01:19

Management of Insomnia

229
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Area of Science:

  • Geriatric Medicine
  • Pharmacology
  • Neurology

Background:

  • A 75-year-old male patient was admitted for geriatric rehabilitation following a fall.
  • Initial symptoms were misdiagnosed as hyperactive delirium.
  • The patient experienced tonic-clonic seizures, prompting a diagnostic review.

Purpose of the Study:

  • To highlight the importance of comprehensive medication history in geriatric patients.
  • To differentiate between delirium and antidepressant withdrawal syndrome.
  • To emphasize the potential for serious adverse events from missed medication information.

Main Methods:

  • Retrospective review of a geriatric rehabilitation patient's case.
  • Analysis of presenting symptoms and diagnostic progression.
  • Identification of a missed high-dose amitriptyline regimen.

Main Results:

  • High-dose amitriptyline use was initially missed in the patient's medication history.
  • Tonic-clonic seizures occurred, leading to a re-evaluation of the initial diagnosis.
  • The patient's condition was reclassified as antidepressant withdrawal syndrome.

Conclusions:

  • Misinterpretation of symptoms can delay accurate diagnosis in elderly patients.
  • Antidepressant withdrawal syndrome can present with severe neurological manifestations.
  • Thorough medication reconciliation is critical to prevent adverse drug events in geriatric care.
