Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Seizures
Abnormal electrical activity in the brain causing seizures.
Seek immediate medical attention if experiencing a seizure for the first time or if seizures last more than 5 minutes.
Severe headache
Sudden, severe headache that may indicate increased intracranial pressure.
Seek immediate emergency care for sudden, worst-ever headache or headache with neurological symptoms.
Cognitive impairment
(neurologic)Difficulty with memory, attention, and executive function due to disrupted subcortical neural pathways.
Frequency: 70-80% of patients
Motor coordination difficulties
(neurologic)Problems with fine motor control, balance, and coordinated movements.
Frequency: 65-75% of patients
Movement abnormalities
(neurologic)Involuntary movements such as tremors, dystonia, or choreiform movements.
Frequency: 40-50% of patients
Fatigue
(constitutional)Persistent tiredness and low energy levels that interfere with daily activities.
Frequency: 45-55% of patients
Speech difficulties
(neurologic)Slurred speech or difficulty with speech articulation due to motor control issues.
Frequency: 20-30% of patients
Behavioral changes
(neurologic)Mood swings, depression, or personality changes related to subcortical dysfunction.
Frequency: 35-45% of patients

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Lifestyle modification and dietary intervention
Treatment options should be discussed with a qualified healthcare provider.
Neuroimaging surveillance
Regular MRI or CT imaging to monitor structural changes in subcortical regions over time, allowing for early detection of progression or complications.
Symptomatic pharmaceutical management
Targeted medication therapy to address specific symptoms such as movement disorders, cognitive changes, or mood disturbances associated with subcortical abnormalities.
Additional treatment options
Neurorehabilitation program
Specialized physical therapy focusing on motor control, balance, and functional movement patterns to address any motor deficits related to subcortical involvement.
physical_therapyNeuroprotective lifestyle modifications
Implementation of cognitive stimulation activities, regular exercise, and sleep optimization to support overall brain health and potentially slow progression.
lifestyleNeuropsychological support
Cognitive behavioral therapy and neuropsychological interventions to address emotional well-being, coping strategies, and cognitive function.
