A brief overview on Neuroleptic Malignant Syndrome presented for the PGs and the faculty of Dept. of Medicine, Govt. Medical College Kannur, Kerala, India
This is a presentation done on 4/6/11 for the Grand Rounds at Wayne State university by Pallav Pareek M.D.
This presentation talks about the concept of prdrome as it is(if?) applicable to schizophrenia, and if schizophrenia is becoming more of a preventable illness as science progresses. If so what are the various ways and means in which we can accomplish this prevention.
Amidst so much controversy on the issue , whether there is a prodrome for this illness or not, here I have tried to present the recent advances in this field and the recent scientific literature in this regard.
TREATMENT RESISTANT DEPRESSION IS A AREA THAT IS NOT EXPLORED MUCH, BUT IT REALLY NEEDS LOT OF ATTENTION AS IT IS ONE OF THE MOST COMMON OBSTACLE IN ACHIEVING COMPLETE REMISSION IN DEPRESSION
Please find the power point on Management of antipsychotic overdose. I tried to present it on understandable way and all the contents are reviewed by experts and from very reliable references. Thank you

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

3. Case Vignette
• A 45 year old woman
• History of BPAD and hypertension
• Hospitalized with depressed mood of one month’s duration.
• In prior episodes, she had received antidepressants, lithium
and ECT.
• On admission, she was excited with idiosyncratic behavior
with confused speech and thought.
4. • Two doses of haloperidol were administered.
• Her excitement subsided.
• She became grandiose, garrulous and paced
continuously.
• Lithium carbonate was prescribed and fluphenazine
hydrochloride (5 mg Q.D.S. daily) was added.
• Within 48 hours, she exhibited bilateral cogwheel
rigidity
• Improved with IM promethazine hydrochloride.
5. • The next day, she became tremulous, had persistent cogwheel
and her temperature rose to 100 F.
• Contemplating neurotoxicity, both lithium and fluphenazine
were discontinued.
• Her condition worsened and she became mute, tremulous and
rigid and diaphoretic.
• B.P. and heart rate increased, temperature rose to 103.5 F.
6. • Lungs clear
• Abdomen- soft, non- tender, nil bowel sounds
• No meningism or focal neurological deficit
• Pupils – normal, reactive
• No clonus
• Reflexes normal
• WBC count was 13,500/ cubic mm and CPK was 1486 IU/l. All
other investigations WNL (including CT Brain and EEG).
How will you manage this case?
8. Introduction
• Rare but potentially life-threatening idiosyncratic reaction
• First description (Delay et al. )- 1960 - Haloperidol
• Incidence – 0.02 to 3 %
• Males > females (3:2)
• Age - < 20 years and > 65 years
• A retrospective study conducted in India showed an
incidence of 0.14%.
Chopra MP, Prakash SS, Raguram R. The neuroleptic malignant syndrome: an Indian
experience. Compr Psychiatry. 1999 Jan-Feb. 40(1):19-23.
9. • NMS usually occurs after exposure to an neuroleptic drug.
• On an average, onset is 4-14 days after the start of therapy
• 90% of cases occur within 10 days.
• NMS can occur years into therapy.
• Once the syndrome starts, it usually evolves over 24-72 hours.
• Mnemonic- “ F.E.V.E.R.”
10. Diagnostic criteria (DSM 5) (all 3 major or 2 major
and 2 minor)
• Major criteria (all required)
1. Exposure to dopamine antagonist
or dopamine agonist withdrawal
with 72hours
2. Muscle rigidity
3. Hyperthermia (>100.4 deg. F or >
38 deg. C, measured orally on at
least two occasions)
• Nierenberg and colleagues’
criteria
• Levenson’s criteria
• Caroff and Mann’s criteria
• Hope’s criteria
• Minor (at least 2 required)
1. Diaphoresis
2. Dysphagia
3. Tremor
4. Incontinence
5. Altered levels of consciousness
6. Mutism
7. Tachycardia
8. Elevated or labile B.P.
9. Leukocytosis
10. Elevated CPK (> 4 times)
13. Rigidity
• Generalized and extreme
• Lead pipe rigidity
• Superimposed on tremors cog- wheel
• Generalized tremors
• Dyskinesia, dysarthria and myoclonus
• Catatonic symptoms (mutism, posturing, waxy
flexibility, catalepsy)
14. Autonomic instability
• Tachycardia (in 88 percent)
• Labile or high blood pressure (in 61 to 77
percent),
• Tachypnoea (in 73 percent)
• Dysrhythmias
• Incontinence
• Diaphoresis- profuse (“greasy” sweat)
15. Hyperthermia
• 100 to 105 degrees F
• May not be evident with second generation
antipsychotics
• May be fluctuating
16.
17. • “Atypical” NMS:
- DSM 5 criteria not met
- Milder form
- Only hyperthermia and/or rigidity
- Clozapine, Aripiprazole and paliperidone
18. Pathophysiology
• Secondary to decreased dopamine (DA) activity in
central nervous system (CNS):
• • Blockade of dopamine type 2 receptors (D2
receptors)
• • Decreased availability of DA itself.
• Direct effect on peripheral skeletal muscles may play
an additive role
19.
20. • Hypothalamic D2 receptor blockade results in an
elevated temperature set point
• Impairment of heat-dissipating mechanisms (eg.
cutaneous vasodilatation, sweating)
• Nigrostriatal blockade results in muscular rigidity.
21. • Peripherally, antipsychotics lead to increased calcium
release from the sarcoplasmic reticulum
• Increased contractility, which can contribute to
hyperthermia, rigidity, and muscle cell breakdown.
• Removing tonic inhibition from the sympathetic
nervous system.
• The resulting sympathoadrenal hyperactivity and
dysregulation leads to autonomic dysfunction.
22. • Animal model studies- orexin-A (an excitatory
neuropeptide) can cause thermogenesis in a
manner unrelated to muscle activity.
• Orexin-1 receptor plays a role in the effects of
psychotropics on dopamine pathways
• And probably the clinical effects of these agents
(therapeutic and side effects).
23. Risk factors
• Genetics
• Young Males
• Dehydration/ malnutrition
• Exposure to high ambient temperatures
• Agitation or excitement
• Catatonic features, past or present
• Tardive dyskinesia, akathisia, EPS
24. Risk factors (contd..)
• Past history of NMS
• Sudden dose escalation of antipsychotics
• High potency antipsychotic or two or more
antipsychotics
• High potency antipsychotic with an
antidepressant or mood stabilizer (lithium)
• IM antipsychotic or depot antipsychotic
• Recent alcohol abuse with liver dysfunction
25. Risk factors (contd..)
• Alcohol use
• Trauma
• Infections
• Thyrotoxicosis,
• Premenstrual/ Post partum phase
26. Early signs

tremors, rigidity, dyskinesia to low or modest
doses of an antipsychotic
• Mania with fever
• Within 24 hours of initial - Catatonia

circulation (ABCs)
• Assess safety and restrain if needed (chemical
preferred)
• Thiamine, dextrose (or rapid glucose
determination), and/or naloxone, in case of
alcohol withdrawal, hypoglycemia, and opioid

• Heparin or low molecular weight heparin for
prevention of deep venous thrombosis
42. • Benzodiazepines
- For mild NMS
- Lorazepam -1 to 2 mg IM or IV every four to
six hours
- Diazepam 5 to 10 mg IV every eight hours.
43. • Bromocriptine mesylate
- Dopamine agonist
- 2.5 mg orally two or three times a day, increased by
2.5 mg per 24 hours to a total daily dose of 45 mg.
- Can worsen psychosis and hypotension.
- Precipitate vomiting - should be used carefully in
patients at risk of aspiration.
- Premature discontinuation results in rebound
symptoms
- Safe in pregnancy
- Continue for 10 days followed by a slow taper to
minimize relapse
44. • Dantrolene
- Direct acting skeletal muscle relaxant
- 1–2.5 mg/kg body weight administered
initially
- followed by 1 mg/kg every 6 hours if rapid
resolution of the fever and rigidity is observed
- Maximum dose- 10 mg/kg
- Taper or switch to oral dantrolene after the
first few days.
- Oral dantrolene doses - 50 to 200 mg/d
45. - Continue for 10 days followed by a slow taper to
minimize relapse
- Side effects may include impairment of
respiratory or hepatic function
- Only in cases of NMS with extreme temperature
elevations, rigidity, and true hypermetabolism
• With depot neuroleptics, treatment should be
continued up to 2–3 weeks beyond clinical
recovery.
46. • Amantadine
- Dopamine agonist
- Initial dose is 100 mg orally or via gastric tube
- Titrate upward as needed to a maximum dose of
200 mg every 12 hours
- Caution- worsening of psychosis
- Levodopa, combined with the dopadecarboxylase
inhibitor carbidopa- effective in reversing
hyperthermia
47. • Serial follow-up of CK and myoglobulin levels.
• Do not suddenly withdraw treatment despite
recovery.
• High chances of recurrence
• With depot neuroleptics, treatment should be
continued up to 2–3 weeks beyond clinical
recovery.
48. • Electro-convulsive therapy (ECT)
- Can help with the alteration of temperature,
level of consciousness, and diaphoresis.
- Effective if symptoms are refractory to
supportive care and pharmacotherapy
- Idiopathic malignant catatonia due to an
underlying psychotic disorder
- persistent residual catatonia and parkinsonism
after resolution of NMS
• Six to 10 treatments with bilateral electrode
placement
49. - It may also be useful in treating the underlying
psychiatric disease in patients who are unable to
take neuroleptics.
- ECT with anesthesia has generally been safe
- No increased incidence of malignant
hyperthermia from succinylcholine
administration.
• Risks- cardiac arrest, ventricular fibrillation and
status epilepticus
50. What will happen if you don’t
intervene?
• Dehydration
• Electrolyte imbalances
• Acute renal failure
associated with
rhabdomyolysis
• Cardiac arrhythmias
including torsade de pointes
and cardiac arrest
• Myocardial infarction
• Cardiomyopathy
• Sepsis
• Reversible dilated
myocardiopathy ( Takotsubo
myocardiopathy)
• Respiratory failure from
chest wall rigidity, aspiration
pneumonia, pulmonary
embolism
• Deep vein thrombosis (DVT)
• Thrombocytopenia
• Disseminated intravascular
coagulation (DIC)
• Seizures from hyperthermia
and metabolic
derangements
• Hepatic failure
51. Restarting of antipsychotics
• Likelihood of developing NMS again as high as
30%
• reports of previous episodes should be
checked for accuracy
• indications for antipsychotics should be clearly
documented
• alternative medications should be considered
• risk factors should be reduced
52. • At least 2 weeks should be allowed to elapse
after recovery from NMS before rechallenge.
• 6 weeks for depot injections
• Low doses of low-potency conventional
antipsychotics or atypical antipsychotics
should be titrated gradually after a test dose.
• Patients should be carefully monitored for
early signs of NMS.
• Documented written consent
53. Prognosis
• Resolve within 2 weeks (reported mean
recovery times are 7–11 days).
• Cases persisting for 6 months with residual
catatonia and motor signs are reported.
• Risk factors for a prolonged course are depot
antipsychotic use and concomitant structural
brain disease.
54. Prognosis
• Most patients recover without neurologic
sequelae
• Except where there is severe hypoxia or
grossly elevated temperatures for a long
duration.
• Reported mortality rates for NMS are 5–20%.
• Disease severity and the occurrence of
medical complications are the strongest
predictors of mortality.
55. Conclusion
• Neuroleptic malignant syndrome is rare but life-
threatening medical emergency
• A diagnosis of exclusion
• Following usage of neuroleptics and abrupt withdrawal
of some drugs.
• Tetrad: Altered mental state, Rigidity, Hyperthermia
and Autonomic dysfunction
• Due to blockade of D2 receptors
• No pathognomonic lab tests.
• Early recognition and prompt treatment has shown
encouraging outcome (reduced mortality).

Neuroleptic malignant syndrome can occur as a result of changes in pre- or postsynaptic DA signaling. There are two mechanisms:
1. Reduced DA signaling resulting from sudden withdrawal of dopaminergic agents
2. Introduction of agents that block DA signaling
