Number of Conditions: 6

Concussion

Specialty: Neurology

Category: Traumatic Brain and Spinal Cord Injuries

Symptoms:
headache; confusion; dizziness; nausea; vomiting; blurred vision; sensitivity to light and noise; memory loss; difficulty concentrating; fatigue

Root Cause:
A mild traumatic brain injury caused by a sudden impact or jolt to the head, leading to temporary disruption of brain function.

How it's Diagnosed: videos
Clinical evaluation (patient history, symptom analysis, and physical examination), neurocognitive testing, imaging tests like CT or MRI (if severe symptoms or risk of complications).

Treatment:
Rest, gradual return to activities, symptom management, cognitive and physical rehabilitation if needed.

Medications:
Pain relievers like acetaminophen or ibuprofen for headaches. Prescription medications, such as amitriptyline (tricyclic antidepressant) or topiramate (antiepileptic), may be used for post-concussion headaches or migraines.

Prevalence: How common the health condition is within a specific population.
Common; estimated 1.6–3.8 million concussions occur annually in the U.S. related to sports and recreational activities.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Participation in contact sports, history of previous concussions, motor vehicle accidents, falls, younger age (children and adolescents).

Prognosis: The expected outcome or course of the condition over time.
Generally good, with most people recovering fully within weeks to months; symptoms may persist longer in post-concussion syndrome.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Post-concussion syndrome, second impact syndrome, chronic traumatic encephalopathy (CTE), persistent cognitive or emotional problems.

Physical and neurological examinations, imaging tests like CT scans or MRIs, Glasgow Coma Scale assessment.

Treatment:
Emergency stabilization, surgical intervention if necessary (to relieve pressure or repair damage), physical and cognitive rehabilitation, supportive care.

Medications:
Diuretics (e.g., mannitol ) to reduce brain swelling; anticonvulsants (e.g., levetiracetam ) to prevent seizures; sedatives (e.g., propofol ) for agitation or to manage intracranial pressure.

Prevalence: How common the health condition is within a specific population.
About 2.8 million emergency department visits for TBI in the U.S. annually; common in all age groups, particularly young adults and the elderly.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Falls, vehicle accidents, sports injuries, physical violence, military combat exposure.

Prognosis: The expected outcome or course of the condition over time.
Varies widely; mild TBIs often resolve fully, while severe TBIs may result in long-term disabilities or death.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Seizures, infections, hydrocephalus, cognitive or emotional impairments, death.

Spinal Cord Injury (SCI)

Specialty: Neurology

Category: Traumatic Brain and Spinal Cord Injuries

Symptoms:
loss of sensation; paralysis; pain; loss of bladder or bowel control; difficulty breathing; spasticity

Root Cause:
Damage to the spinal cord due to trauma, leading to partial or complete disruption of nerve signals between the brain and body.

How it's Diagnosed: videos
Neurological examination, imaging tests like MRI or CT scan, and functional assessments.

Treatment:
Emergency stabilization, surgery to repair or decompress the spinal cord, physical therapy, occupational therapy, assistive devices.

Medications:
High-dose corticosteroids (e.g., methylprednisolone ) in some cases for inflammation; pain relievers (e.g., gabapentin for neuropathic pain); antispasmodics (e.g., baclofen ) for spasticity.

Prevalence: How common the health condition is within a specific population.
Around 17,900 new cases in the U.S. annually; prevalence of approximately 300,000 individuals living with SCI.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Motor vehicle accidents, falls, sports injuries, violence (e.g., gunshot wounds), medical conditions like spina bifida.

Prognosis: The expected outcome or course of the condition over time.
Depends on the level and severity of the injury; partial recovery possible in some cases, but permanent disability is common.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Pressure ulcers, respiratory issues, urinary tract infections, chronic pain, depression.

Subdural Hematoma

Specialty: Neurology

Category: Traumatic Brain and Spinal Cord Injuries

Symptoms:
headache; confusion; drowsiness; vomiting; seizures; weakness; slurred speech; loss of consciousness

Root Cause:
Bleeding between the dura mater and the arachnoid membrane, typically caused by trauma to the head.

How it's Diagnosed: videos
Diagnosed through neuroimaging, primarily CT scans or MRI, to detect blood accumulation.

Treatment:
Treatment ranges from observation for mild cases to surgical intervention (craniotomy or burr hole drainage) for severe cases.

Medications:
Antiepileptic drugs (AEDs) such as levetiracetam or phenytoin may be prescribed to prevent seizures. Pain management medications like acetaminophen are also used.

Prevalence: How common the health condition is within a specific population.
Subdural hematomas are relatively common, especially among older adults and individuals on anticoagulant therapy.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Head trauma, older age, use of blood thinners, alcohol abuse, and brain atrophy.

Prognosis: The expected outcome or course of the condition over time.
Variable depending on severity and treatment; mild cases have a good prognosis, but severe cases can lead to permanent neurological impairment or death.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Increased intracranial pressure, brain herniation, chronic subdural hematoma, seizures, and cognitive deficits.

Epidural Hematoma

Specialty: Neurology

Category: Traumatic Brain and Spinal Cord Injuries

Symptoms:
brief loss of consciousness followed by a lucid interval; headache; vomiting; confusion; weakness; seizures; unequal pupil size; progressive loss of consciousness

Root Cause:
Accumulation of blood between the skull and dura mater, often due to the rupture of an artery, commonly the middle meningeal artery, from trauma.

How it's Diagnosed: videos
Diagnosed through CT scans or MRI to visualize blood collection.

Treatment:
Emergency surgical evacuation of the hematoma via craniotomy or burr hole surgery.

Medications:
Anticonvulsants like levetiracetam to prevent seizures and analgesics for pain management.

Prevalence: How common the health condition is within a specific population.
Less common than subdural hematomas but more frequently observed in younger patients with head trauma.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Skull fractures, head trauma, high-impact injuries, and anticoagulant therapy.

Prognosis: The expected outcome or course of the condition over time.
Good if treated promptly; untreated cases can lead to brain herniation and death.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Increased intracranial pressure, brain herniation, permanent neurological deficits, and death if untreated.

Diffuse Axonal Injury (DAI)

Specialty: Neurology

Category: Traumatic Brain and Spinal Cord Injuries

Symptoms:
loss of consciousness; vegetative state; persistent headaches; memory loss; difficulty concentrating; mood changes; motor and sensory deficits

Root Cause:
Widespread shearing and tearing of axons in the brain due to rapid acceleration or deceleration, typically seen in severe traumatic brain injuries.

How it's Diagnosed: videos
Diagnosed using advanced imaging techniques like MRI (particularly DTI) and clinical evaluation of symptoms.

Treatment:
Supportive care, including maintaining oxygenation, managing intracranial pressure, physical rehabilitation, and occupational therapy.
