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)

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
