Precision Medicine in Neurology: Personalized Approaches to Diagnosis and Treatment

Precision Medicine in Neurology: Personalized Approaches to Diagnosis and Treatment

  Category: Blog     Date: 07-06-2023  

Neurological and psychiatric diseases are quite complex, and they vary a lot in terms of genetics and how they affect the body. Typically, doctors have focused on the visible signs of these diseases and haven't paid as much attention to the underlying biology. 

But now, thanks to advancements in disease research and technology, a new approach called precision medicine is emerging. Precision medicine has been successful in neurology treatment.

What is precision medicine?

Precision medicine, or personalized approaches, is a special way of treating diseases that considers each person's unique characteristics. It's like getting a treatment plan made just for you. Let's take a look at an example in the world of neurological diseases.

Imagine two people who both have Parkinson's disease, a condition that affects movement and coordination. With precision medicine, neurology doctors would study each person's genes to understand how their bodies are different. They might find that one person has a specific gene that causes their symptoms to progress more quickly. Based on this information, the doctor can create a personalized treatment plan.

For example, the doctor might prescribe a medication that targets the specific gene in the person with faster progression, while using a different medication for the other person. This way, each person gets the best treatment for their individual needs.

What is precision medicine in neurology?

By understanding the unique characteristics of a patient's neurological condition, such as genetic predispositions, biomarkers, and disease mechanisms, precision medicine aims to optimize treatment outcomes and improve patient care.

Healthcare providers can develop more accurate diagnoses, design personalized treatment plans, minimize adverse effects, and potentially enhance the overall quality of life for individuals with neurological disorders by considering personalized factors.

Overall, precision medicine in neurology holds the promise of advancing our understanding of neurological diseases and transforming healthcare by tailoring interventions to the unique needs of each patient.

Benefits of personalized medicine in patient care

Personalized medicine plays a crucial role in striving for more precise, predictable, and robust healthcare for every patient. 

By deepening our understanding of genetics and genomics, particularly in how individuals respond to drugs and diseases, doctors can improve disease prevention, enhance diagnostic capabilities, prescribe safer medications, and deliver more effective treatments.

Personalized medicine offers several advantages for healthcare providers:

  • Shifting the focus from reacting to diseases towards prevention.

  • Predicting an individual's susceptibility to diseases.

  • Enhancing disease detection and diagnosis.

  • Proactively intervention to halt the progression of diseases.

  • Tailoring disease-prevention strategies based on individual needs.

  • Improving the effectiveness of prescription drug usage.

  • Preventing the prescription of drugs with known side effects for a particular individual.

  • Saving time and reducing overall healthcare costs.

At its core, personalized medicine revolves around tailoring healthcare services based on a person's unique genetic characteristics. It is also referred to as individualized medicine, precision medicine, or "genetic medicine. 

Personalized Approaches to Diagnosis and Treatment of Neurological disorder

Applying a precision medicine approach to diagnose and treat neurological disorders involves several key steps:

  1. Molecular Profiling: Analyzing the genetic and molecular characteristics of a patient's neurological disorder. This may include conducting genetic testing, examining biomarkers, or performing molecular imaging to identify specific abnormalities or variations.

Example: In the case of epilepsy, genetic testing can help identify specific gene mutations associated with the disorder, enabling more accurate diagnosis and targeted treatment selection.

  1. Clinical Evaluation: Conducting a comprehensive assessment of the patient's medical history, symptoms, and neurological examination to gather relevant clinical information.

Example: For a patient with Parkinson's disease, a thorough evaluation of motor symptoms, family history, and response to medication can guide treatment decisions.

  1. Personalized Diagnosis: Integrating genetic and clinical information to make a precise diagnosis and classify the specific subtype of the neurological disorder.

Example: In multiple sclerosis (MS), precision medicine can help determine the subtype of MS (such as relapsing-remitting or progressive) based on genetic and clinical factors, allowing for tailored treatment approaches.

  1. Targeted Treatment Selection: Using the patient's unique characteristics, such as genetic profile and clinical features, to guide the selection of treatments that are most likely to be effective and minimize adverse effects.

Example: In Alzheimer's disease, genetic testing can identify specific genetic risk factors, allowing for the use of precision-targeted therapies that aim to slow disease progression.

  1. Monitoring and Adjustment: Regularly monitoring the patient's response to treatment using personalized biomarkers or clinical indicators, and adjusting the treatment plan as needed to optimize outcomes.

Example: For a patient with migraines, tracking patterns and triggers using digital health technologies can help identify personalized treatment strategies and lifestyle modifications to reduce the frequency and severity of attacks.

By applying these steps, precision medicine enables more accurate diagnoses, personalized treatment plans, and better management of neurological disorders, leading to improved patient outcomes.


In the advanced era of technology and knowledge, the most difficult and unrecognizable diseases can now be cured, stopped, and reversed with the help of expert doctors, research teams, and advanced technology. Apollo Hospital in Patna is considered an "advanced neuro hospital in Patna where patients get treatment from Apollo’s best neurologist in Patna.
