Brain calcifications, or "brain stones," may cause neurological issues. Treatment with bisphosphonates, drugs typically for bone diseases, showed preliminary success in improving symptoms like seizures and parkinsonism.
Area of Science:
- Neuroscience
- Nephrology
- Pharmacology
Background:
- Perivascular calcifications in the brain, termed
- brain stones
- are calcium phosphate deposits that can form due to various insults.
- While often considered benign, they can enlarge and correlate with neurological deficits.
Observation:
- High calcium concentrations in brain calcifications may exert reversible toxic effects on neurons.
- These deposits are associated with progressive neurological symptoms, including seizures and parkinsonism.
Findings:
- Preliminary data indicate a direct link between brain calcification progression and worsening neurological symptoms.
- Patients treated with disodium etidronate, a bisphosphonate drug, experienced symptomatic improvement in seizures, headaches, and parkinsonian symptoms.
Implications:
- Bisphosphonates, used for bone diseases, show potential in managing neurological symptoms associated with brain calcifications.
- Further longitudinal studies and randomized trials are necessary to confirm the efficacy of bisphosphonates for brain stone treatment and prevention.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
