Cerebral Causes of Paraplegia

Introduction to Cerebral Causes

The primary approach to managing cerebral causes of paraplegia should focus on early diagnosis, prompt treatment of the underlying cerebral pathology, and implementation of targeted rehabilitation to maximize neurological recovery and prevent complications, as recommended by general medical guidelines 1
Metastatic brain tumors affecting motor cortex can cause paraplegia, according to the National Comprehensive Cancer Network 2
Intracerebral hemorrhage affecting bilateral motor cortex is a cerebral cause of paraplegia, as reported in Circulation 3
Neuroschistosomiasis with cerebral involvement and neurocysticercosis causing hydrocephalus are less common cerebral causes of paraplegia, as noted in the Journal of Infection 1

Lumbar puncture is recommended for suspected infectious causes, such as neurocysticercosis or schistosomiasis, as stated in the Journal of Infection 1
Serology is used for diagnosing parasitic infections like neuroschistosomiasis, according to the Journal of Infection 1

The following imaging protocols are recommended:

Imaging Modality	Indication
CT brain	Initial assessment of head injury
CT cervical spine	Initial assessment of cervical spine injury
CT angiography	Patients with risk factors for vascular injury
MRI	Detecting hemorrhagic axonal injuries

Targeted examination of the supra-aortic and intracranial arteries using CT angiography is recommended in patients with risk factors such as cervical spine fracture, focal neurological deficits, or skull base fractures 4

Control of seizures with anticonvulsants is recommended for patients with a history of seizures, as advised by the National Comprehensive Cancer Network 2
Management of cerebral edema with dexamethasone (starting at 4-8 mg/day) is suggested for patients with cerebral causes of paraplegia, according to the National Comprehensive Cancer Network 2
Definitive treatment options for metastatic brain tumors include surgical resection, stereotactic radiosurgery, whole brain radiation therapy, and combination approaches based on tumor characteristics, as recommended by the National Comprehensive Cancer Network 2
Albendazole (400 mg twice daily for 14 days) with dexamethasone (4-12 mg/day, reducing after 7 days) is recommended for neurocysticercosis, as stated in the Journal of Infection 1
Praziquantel 40 mg/kg twice daily for 5 days is recommended for neuroschistosomiasis, according to the Journal of Infection 1
The American College of Emergency Physicians suggests that an intracranial displacement exceeding 1cm typically necessitates surgical management, with the presence of extra-axial collection and hemorrhagic contusions further supporting this indication 6, 7
The American Association of Neurological Surgeons recommends craniotomy with elevation of the depressed fragment, debridement of the wound if compound fracture, repair of any dural tears, evacuation of associated hematomas, and considers single-stage reconstruction with titanium mesh for compound fractures 6

Early intervention with rehabilitation as soon as medically stable is recommended to maximize neuroplasticity, as suggested in JAMA Pediatrics 8
Task-specific, motor training-based interventions are recommended as the new paradigm of care because they induce neuroplasticity and produce functional gains, according to JAMA Pediatrics 8
The Goals-Activity-Motor Enrichment (GAME) approach is an early, intense, enriched, task-specific, training-based intervention that has shown better motor and cognitive outcomes, as reported in JAMA Pediatrics 8
Home-based intervention is recommended when possible, as patients learn best in supported natural settings where training is personalized, according to JAMA Pediatrics 8
Regular surveillance is necessary for patients with bilateral cerebral palsy to prevent complications like hip displacement, contracture, and scoliosis, as advised in JAMA Pediatrics 8
Multidisciplinary rehabilitation programs should be implemented to address physical, cognitive, and behavioral deficits, as suggested by the American Academy of Physical Medicine and Rehabilitation 4
Continue rehabilitation efforts even in chronic cases, as recommended by the American Academy of Physical Medicine and Rehabilitation 4

Prognosis varies significantly based on underlying etiology, extent of cerebral damage, timeliness of intervention, age, and comorbidities, as well as access to appropriate rehabilitation services, as noted in the Journal of Infection 1
Prognosis is poor in cysticercal meningitis, particularly with acute hydrocephalus, according to the Journal of Infection 1

The Neurocritical Care Society suggests considering ICP monitoring if GCS ≤8 with abnormal CT findings, evidence of mass effect, or basal cistern compression, and using CSF drainage via external ventricular drain if hydrocephalus is present 4
Elevating the head of bed 20-30° to improve venous drainage, maintaining euvolemia, treating fever and seizures, and using osmotic therapy with mannitol (0.25-1 g/kg IV) are recommended first-line and second-line measures 4
The American College of Surgeons recommends maintaining a cerebral perfusion pressure (CPP) of ≥60 mmHg, and elevating the head of the bed 20-30° to improve jugular venous flow and reduce ICP 4
Midazolam or propofol should be used as primary sedative agents, with ketamine considered for analgesia as needed, according to the Society of Critical Care Medicine and the American Society of Anesthesiologists 4, 9
DVT prophylaxis, stress ulcer prophylaxis, seizure prophylaxis, normothermia maintenance, and glycemic control are important for preventing complications, as recommended by the Brain Trauma Foundation 4
Anticoagulation with low molecular weight heparin (LMWH) should be started as soon as possible after diagnosis, ideally within 9 hours, in patients with stable intracranial bleeding 4
