Drug-induced Akathisia: An Obsolete but Still Relevant Condition

Akathisia, a condition characterized by an uncomfortable feeling of inner restlessness and inability to stay still, is often associated with the use of antipsychotic medications. This side effect can be distressing for patients and may lead to poor drug compliance.

• Prevalence: Akathisia has been documented as a common side effect of antipsychotics, affecting up to 35% of patients treated with these medications [8].
• Causes: The condition is more commonly linked to the use of first-generation antipsychotic (FGA) medications, particularly high-potency drugs and high-dose drugs, than second-generation antipsychotics (SGAs) [2].
• Symptoms: Patients experiencing akathisia may exhibit restlessness, agitation, and an inability to stay still, which can be distressing and affect their quality of life.
• Diagnosis: Despite its prevalence, akathisia is often misdiagnosed or under-recognized in clinical settings, with one study finding that it was diagnosed in only 26% of patients who had the condition [3].
• Treatment: Propranolol has been shown to be effective in treating neuroleptic-induced akathisia [9].

It's essential for healthcare providers to recognize and accurately diagnose akathisia to provide appropriate treatment and management. This can help alleviate symptoms, improve patient compliance, and enhance overall well-being.

Common Signs and Symptoms of Obsolete Drug-Induced Akathisia

Akathisia, a condition induced by certain medications, is characterized by a range of physical and psychological symptoms. The following are some common signs and symptoms associated with obsolete drug-induced akathisia:

• Motor Restlessness: A subjective feeling of inner restlessness accompanied by an inability to sit still or remain motionless [5][10].
• Repetitive Movement: Compulsive movement, often involving the lower extremities, such as shifting weight from one leg to another, crossing and uncrossing legs, or rocking back and forth [1][2][7].
• Fidgeting and Pacing: Restlessness that manifests through fidgeting, pacing, or other forms of repetitive movement [3][13].
• Inability to Sit or Stand Still: A persistent urge to move, making it difficult for individuals to sit or stand still for extended periods [10][14].
• General Feelings of Terror and Franticness: Some people may experience intense feelings of terror, anxiety, or franticness, which can exacerbate the distress associated with akathisia [13].

Less Common Features

In addition to these common symptoms, some individuals may also exhibit less common features, such as:

• Depersonalization: Feelings of detachment from oneself or one's surroundings [13].
• Psychological Symptoms: A range of psychological symptoms, including anxiety, depression, and other mood disturbances, can manifest alongside the physical symptoms of akathisia [14].

Prevalence

Akathisia is a relatively common side effect of certain medications, particularly older antipsychotic drugs. Studies suggest that between 15% to 45% of people who take these medications may experience akathisia [15].

Diagnostic Tests for Obsolete Drug-Induced Akathisia

Akathisia, a movement side effect associated with antipsychotic medication, has been a subject of study for decades. While the Barnes Akathisia Rating Scale (BARS) is currently the most widely used diagnostic tool, there were other tests and scales used in the past to assess drug-induced akathisia.

• The BARS: Developed by TRE Barnes in 1989, the BARS is a rating scale that measures both objective signs and subjective symptoms of akathisia. It has been widely used and cited in research studies (6, 5).
• Other pre-clinical animal tests: Additional tests proposed to model akathisia include the SSRI-induced restlessness model, dopamine agonist and antagonist-induced restlessness tests in non-human primates, and the hyperkinesia dog model. However, these tests are considered less optimal for studying akathisia (10).
• The American Psychiatric Association's DSM-5 criteria: The Diagnostic and statistical manual of mental disorders, 5th edition (DSM-5), describes medication-induced acute akathisia as a condition characterized by restlessness or the need to move frequently, accompanied by an unpleasant subjective sensation in the lower limbs (8).

Key Points:

• The BARS is currently the most widely used diagnostic tool for assessing drug-induced akathisia.
• Other pre-clinical animal tests have been proposed to model akathisia but are considered less optimal.
• The DSM-5 criteria describe medication-induced acute akathisia as a condition characterized by restlessness or the need to move frequently, accompanied by an unpleasant subjective sensation in the lower limbs.

Treatment Options for Obsolete Drug-Induced Akathisia

Akathisia, a movement disorder characterized by restlessness and an inability to sit still, is often induced as a side effect of certain medications, including antipsychotics. When the causative medication is discontinued or replaced with another type of drug, treatment options for akathisia may be considered.

• Dose reduction: Reducing the dose of the original antipsychotic medication can sometimes alleviate akathisia symptoms [12].
• Switching to a low-potency FGA: Switching from a high-potency first-generation antipsychotic (FGA) to a low-potency FGA may also be effective in reducing akathisia symptoms [12].
• Adding an anti-akathisia agent: In some cases, adding an anti-akathisia agent, such as benzodiazepines or anticholinergic drugs, may be necessary to manage akathisia symptoms [13].

Important Considerations

When considering treatment options for obsolete drug-induced akathisia, it is essential to weigh the potential benefits against the risks and side effects of each approach. For example:

• Benzodiazepines: While benzodiazepines may provide temporary relief from akathisia symptoms, their use can be associated with dependence and withdrawal symptoms [2].
• Anticholinergic drugs: Anticholinergic drugs may also have side effects, such as dry mouth, constipation, and confusion, which must be carefully considered in the treatment plan [3].

Akathisia, a neuropsychiatric syndrome characterized by an intense sensation of unease or inner restlessness, can be challenging to diagnose accurately. When considering the differential diagnosis for obsolete drug-induced akathisia, several conditions come into play.

• Restless Legs Syndrome (RLS): This condition is often confused with akathisia due to its similar symptoms, such as an inability to keep still and a strong urge to move the legs. However, RLS typically affects the legs only, whereas akathisia can involve any part of the body.
• Parkinsonism: This neurological disorder shares some similarities with akathisia, including restlessness and difficulty with movement. However, parkinsonism is characterized by tremors, stiffness, and bradykinesia (slow movement), which are not typically seen in akathisia.
• Tardive Dyskinesia: This condition involves involuntary movements of the face, trunk, or limbs, often caused by long-term use of antipsychotic medications. While it can be mistaken for akathisia, tardive dyskinesia is usually more severe and involves a wider range of motor symptoms.
• Agitation and Anxiety: These conditions can also present with restlessness and an inability to keep still, making them potential differential diagnoses for obsolete drug-induced akathisia. However, they are typically accompanied by other symptoms such as irritability, mood swings, or panic attacks.

To accurately diagnose obsolete drug-induced akathisia, it is essential to consider the patient's medical history, medication regimen, and symptom profile. A thorough evaluation by a qualified healthcare professional is necessary to rule out these differential diagnoses and provide an accurate diagnosis.
