Managing Chronic Migraines: A Guide to Preventive Treatments
For those who are regularly plagued by debilitating headaches, seeking help from a headache specialist could be a crucial step towards finding relief. These medical professionals are equipped to establish the right treatment plan for managing chronic migraines, a condition that currently has no cure.
The treatment approach often involves a combination of acute and preventive measures, which may include oral or injectable medications. However, it's important to note that overuse of acute migraine medications can worsen symptoms, and so a proactive approach is key.
Keeping a record of factors that trigger migraine attacks and then avoiding these triggers can be a helpful part of migraine care and prevention. Common triggers include higher levels of female sex hormones, depression, anxiety, stress, other pain disorders, conditions that create metabolic strain, such as obesity or sleep apnea.
Preventive migraine medications work by targeting various biological pathways involved in migraine generation. The main mechanisms include:
- Blocking or modulating calcitonin gene-related peptide (CGRP) activity: CGRP is a neuropeptide that contributes to migraines by causing cerebral blood vessel dilation, neurogenic inflammation, and nerve sensitization. CGRP monoclonal antibodies and CGRP receptor antagonists, such as erenumab, fremanezumab, galcanezumab, and atogepant, prevent CGRP from triggering these migraine processes, leading to fewer and less severe attacks.
- Inhibiting neurotransmitter release and nerve sensitization: OnabotulinumtoxinA (Botox), approved for chronic migraine, blocks release of neurotransmitters from sensory neurons, reducing pain signaling and neurogenic inflammation. This action provides both anti-pain and preventive effects in migraine.
- Modulating neuronal excitability and vascular responses: Oral preventives such as beta-blockers (propranolol), anticonvulsants (topiramate, valproate), tricyclic antidepressants (amitriptyline), and calcium channel blockers (verapamil) were initially developed for other conditions but reduce migraine susceptibility by stabilizing neuronal excitability, altering pain pathways, and affecting cerebral blood flow.
These preventive medications are typically taken daily and require several weeks (4–8 weeks) to show effectiveness. Newer CGRP-targeting therapies show promise in being highly specific and effective with fewer side effects compared to traditional preventives.
The goal of chronic migraine treatment is to control symptoms and reduce the impact of the condition on daily living. People with chronic migraine may experience periods of reduced headache burden, returning to a state of episodic migraine. By acting on these pathways, preventive treatments lessen the number of migraine days and reduce intensity, improving quality of life and reducing reliance on acute medications.
In essence, preventive migraine drugs work by interfering with migraine pathophysiology—particularly CGRP signaling, neuronal excitability, and neurogenic inflammation—to lessen chronic migraine attack frequency and severity. It's important for people to be proactive and advocate for themselves during the migraine treatment process.
- A headache specialist, who is knowledgeable in managing chronic migraines, may suggest preventive treatments as part of the treatment plan for those suffering from this debilitating neurological disorder.
- Sciencially developed medications, such as erenumab and fremanezumab, target the calcitonin gene-related peptide (CGRP) pathway, which is known to contribute to migraines, thereby reducing the frequency and severity of these attacks.
- People with chronic migraine often benefit from taking preventive medications such as propranolol, topiramate, amitriptyline, verapamil, and the more recent CGRP-targeting therapies daily for several weeks, as these can significantly reduce the number of migraine days and the intensity of attacks.
- By being proactive in understanding and avoiding triggers for migraines, such as stress or hormonal changes, and by advocating for themselves during the treatment process, individuals with chronic migraine can better manage their health-and-wellness, improve their quality of life, and reduce dependence on acute medications for symptom relief.
