Most common cause of arrhythmic cardiac syncope
Atrioventricular block
Most common arrhythmias causing syncope
AV block
Most common congenital malformation causing syncope
Tetralogy of Fallot
Most common symptom of colloid cysts of the third ventricle
Position-induced headaches
Unprovoked falling – second most common symptom
Most common behavioral disorder in a medical-surgical setting
Delirium
Most common cause of delirium in elderly
Metabolic disturbances,
Most common cause of delirium in young individuals
Drug abuse and alcohol withdrawal
Most common causes of decreased respiratory rate
Metabolic or toxic, such as carbon dioxide narcosis or drug overdose with central nervous system (CNS) depressants.
Most common source of underlying infection in brain abscess
Infections of the middle ear, mastoid, and paranasal sinuses
Ocular bobbing
Ocular bobbing – rapid downward jerks of both eyes are observed, followed by a slow
return to the midposition.
Typical Ocular bobbing
Typical Ocular bobbing – there is associated paralysis of both reflex and spontaneous horizontal eye
movements.
Typical ocular bobbing is specific but not pathognomonic for acute pontine lesions.
Atypical ocular bobbing
Occurs with anoxia
It is nonlocalizing
Inverse ocular bobbing – Ocular dipping
Spontaneous eye movements in which an initial slow downward phase is followed by a relatively rapid return.
Reflex horizontal eye movements are preserved. It usually is associated with diffuse cerebral damage.
Reverse ocular bobbing –
slow initial downward phase, followed by a rapid return that carries the eyes past the midposition into full upward gaze. Then the eyes slowly return to the midposition
NINDS-AIREN diagnostic criteria is used for
vascular dementia
What is the most common psychiatric disturbance in persons with Parkinson Disease?
Depression
What is the most common behavioral symptom in Multiple Sclerosis?
Depression
Most common neuropsychiatric outcomes of stroke
Depression
Anosognosia
It is a neurological condition in which the patient is unaware of their neurological deficit or psychiatric condition.
Which circuits are most commonly implicated in neuropsychiatric symptoms?
Limbic system and the frontosubcortical circuits
Which is the most common human prion disease?
Creutzfeldt–Jakob disease
Most common sign of vitamin B12 deficiency is –
macrocytic anemia
What is the triad of Porphyric attacks ?
- Abdominal pain
- Peripheral neuropathy
- Neuropsychiatric symptoms.
Most common primary malignancies that promote neurological paraneoplastic syndromes are
Ovarian cancer and Small-cell lung cancer
Most common intracranial primary tumors are
Astrocytomas (e.g., glioblastoma multiforme)
Postictal psychosis is most commonly associated with
Temporal lobe epilepsy.
What is the most common site of hypertensive intracerebral hemorrhage?
Putamen
What is the most common form of motor neuron disease?
Amyotrophic lateral sclerosis
