Study Notes
Medial Medullary Syndrome
- Location: Middle region of the medulla oblongata
- Cause: Vertebral artery damage
- Symptoms:
- Contralateral hemiparesis (difficulty or inability to move) due to corticospinal/pyramidal tract damage
- Contralateral loss of tactile discrimination, vibration, fine touch, proprioception etc. due to dorsal column medial lemniscus damage
- Ipsilateral paralysis of tongue and tongue deviation to the paralyzed side due to hypoglossal nerve damage
Weber Syndrome
- Location: Front region of the midbrain
- Cause: Posterior cerebral artery (branch of Basilar artery) damage
- Symptoms:
- Ipsilateral ophthalmoplegia, eyeball deviated towards the right due to medial rectus muscle paralysis, ptosis (drooping eyelid) due to levator palpebrae superioris muscle paralysis due to oculomotor nerve damage
- Light accommodation reflex gone due to Edinger-Westphal nucleus damage
Benedict Syndrome
- Location: Middle region of the midbrain
- Cause: Posterior cerebral artery (branch of Basilar artery) damage
- Symptoms:
- Contralateral hemianesthesia (loss of sensation) due to medial lemniscus damage
- Contralateral involuntary limb movements due to red nucleus damage
Cerebellar Disease
- Location: Cerebellum
- Cause: Damage to any area of the cerebellum
- Symptoms:
- Hypotonia (decreased muscle tone)
- Change in posture and gait
- Ataxia (disturbance of voluntary movement)
- Dysdiadochokinesia (inability to perform rapidly alternating movements)
- Disturbances of reflexes
- Nystagmus (involuntary rapid eye movements)
- Dysarthria (difficulty speaking)
Types of Cerebellar Syndromes
- Vermis Syndrome: Symptoms mainly seen in the trunk and head
- Cerebellar Hemisphere Syndrome: Symptoms mainly seen in the limbs and phonation (articulating speech)
Aphasia
- Types:
- Expressive Aphasia (Broca's Aphasia): Damage to Broca’s motor speech area, loss of ability to speak
- Receptive Aphasia (Wernicke’s Aphasia): Damage to Wernicke’s sensory speech area, loss of ability to understand speech
- Global Aphasia: Both expressive and receptive aphasia together, both Wernicke and Broca areas damaged
Schizophrenic
- Symptoms:
- Disordered thinking
- Emotional withdrawal
- Blunted affect (lack of emotional expression)
- Paranoid delusions
- Auditory hallucinations
Kluver-Bucy Syndrome
- Location: Amygdaloid complex
- Cause: Destruction of the amygdaloid complex
- Symptoms:
- Decreased anger
- Decreased fear
- Decreased restlessness
- Increased appetite
- Increased sexual activity
Basal Nuclei Disorders
- Types:
- Hyperkinetic (Excessive abnormal movements):
- Chorea (involuntary jerky movements)
- Athetosis (slow, writhing movements)
- Ballismus (violent, flinging movements)
- Parkinsonism (tremors, rigidity, slow movements)
- Hypokinetic (Lack or slowness of movements):
- Parkinsonism (tremors, rigidity, slow movements)
- Hyperkinetic (Excessive abnormal movements):
Headaches:
- Meningeal Headache: Damage to the dura mater causing referred pain along the trigeminal nerve
- Cerebral Tumor Headache: Stretching of the dura matter
- Migraine Headache: Multiple reasons causing dilation and constrictions of cerebral arteries
- Alcoholic Headache: Toxic effect on the meninges
- Diseases of Teeth, Eye or Sinus Headache: Referred pain by the trigeminal nerve
Hydrocephalus
- Location: Skull
- Cause: Increased CSF volume and pressure in the skull due to overproduction, reduced drainage, or blockage
- Types:
- Communicating Hydrocephalus: No obstruction present, CSF circulates freely through the ventricles and subarachnoid space
- Non-communicating Hydrocephalus: Obstruction present which prevents circulation between ventricles and the subarachnoid space
Lumbar Puncture
- Location: Between L4-L5 vertebrae
- Structures Pierced:
- Skin
- Superficial fascia
- Deep fascia
- Vertebral ligaments
- Dura matter
- Subdural space
- Arachnoid matter
Cerebral Artery Syndrome
- Cause: Damage to the named areas, which causes infarction (death) of the corresponding brain tissue
- Anterior Cerebral Artery:
- Lobe: Paracentral Lobe
- Symptom: Contralateral hemiparesis (difficulty or inability to move) and hemisensory loss (loss of sensation) of the leg and foot
- Middle Cerebral Artery:
- Lobe: Precentral, postcentral, and frontal lobe
- Symptom: Contralateral hemiparesis and hemisensory loss of the arms and face
- Posterior Cerebral Artery:
- Lobe: Occipital Lobe
- Symptom: Contralateral homonymous hemianopia (loss of half of the visual field in both eyes on the same side)
- Internal Carotid Artery:
- Lobe: Anterior part of the cerebrum
- Symptom: Symptoms of middle cerebral artery and anterior cerebral artery
- Vertebrobasilar Artery:
- Lobe: Brainstem and occipital lobe
- Symptom: Medial and Lateral Medullary syndromes, Benedict and Weber syndromes
Extracranial Hemorrhage
- Types:
- Epidural Hemorrhage
- Subdural Hemorrhage
- Subarachnoid Hemorrhage
- Cerebral Hemorrhage
Epidural Hemorrhage
- Location: Between periosteal and meningeal layer of the dura matter
- Vessel: Anterior branch of middle meningeal artery
- Cause: Blunt trauma
- Symptoms: Lucid interval (temporary recovery of consciousness followed by loss of consciousness), progressively increasing intervals of unconsciousness
Subdural Hemorrhage
- Location: Between dura matter and arachnoid matter
- Vessel: Cerebral/bridging vein
- Cause: Elderly people moving their head suddenly
- Symptoms: Varies
Subarachnoid Hemorrhage
- Location: Between arachnoid matter and pia matter
- Vessel: Circle of Willis
- Cause: Hypertension
- Symptoms: Severe and sudden headache
Cerebral Hemorrhage
- Location: Within the cerebrum
- Vessel: Capillaries of the cerebrum
- Cause: Hypertension
- Symptoms: Depends on the location of the hemorrhage
