Neurological disorders are conditions affecting the brain, spinal cord, and peripheral nerves that cause symptoms like tremors, weakness, and balance problems. They are caused by factors including medication toxicity (such as lithium), viral infections like Human T-Cell Lymphotropic Virus, and metabolic imbalances. The Lithium test is the most important test for diagnosing lithium-induced neurotoxicity, which can cause permanent neurological damage if left untreated.

Neurological disorders are caused by a variety of factors including medication toxicity, viral infections, autoimmune conditions, metabolic imbalances, and genetic factors. Lithium medication, commonly used for bipolar disorder, can cause neurotoxicity when blood levels become too high, leading to tremors, coordination problems, and potentially permanent nerve damage. Viral infections like Human T-Cell Lymphotropic Virus (HTLV-I and HTLV-II) can invade the nervous system and trigger inflammatory responses that damage nerve tissue. Other causes include vitamin B12 deficiency, thyroid disorders, heavy metal exposure, and electrolyte imbalances that disrupt normal nerve function.
The Lithium test is the most important blood test for neurological disorders in patients taking lithium medication because it detects toxic levels that cause tremors, muscle weakness, balance problems, and permanent nerve damage. For patients with unexplained neurological symptoms and potential exposure risks, the Human T-Cell Lymphotropic Virus I, II (HTLV-I/HTLV-II) Qualitative test is essential because it identifies viral infections associated with neurological complications. These blood tests work alongside clinical examinations and imaging studies to identify treatable underlying causes of neurological symptoms. While most neurological conditions require specialized neurological testing, these blood tests detect critical toxicities and infections that, when caught early, can prevent progression of nerve damage.
You should get tested if you are taking lithium medication and experience tremors, muscle twitching, confusion, or coordination problems, as these may signal dangerous toxicity levels. Testing is also important if you develop unexplained neurological symptoms like persistent weakness, numbness, balance issues, or difficulty walking, especially if you have risk factors for viral infections. Anyone on long-term lithium therapy should get regular monitoring every few months to prevent neurotoxicity. If you notice sudden changes in your neurological function or worsening symptoms despite treatment, immediate testing can help identify reversible causes before permanent damage occurs.

What this means
Your lithium level is slightly below the therapeutic range. While not dangerously low, this level may not be fully effective in stabilizing mood and preventing manic or depressive episodes. Your doctor may need to adjust your dose to bring levels into the optimal range.
Recommended actions
Contact your prescribing doctor to discuss a possible dose adjustment
Take your medication at the same time each day for consistent levels
Stay well-hydrated and maintain consistent salt intake
Retest in 5-7 days after any dose changes to ensure proper levels
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
