Headaches: Causes, Management, and Diagnosis

Common causes of headaches and their management

• Tension headache: A tension headache is the most common form of head discomfort marked by a mild to moderate and generally constant pain. Typically, these headaches impact both sides of the head and often resemble a sensation of tightness or pressure encircling the forehead or the rear of the head and neck. These headaches can be triggered by stress (emotional/physical). Management includes lifestyle changes, better diet, more physical activity, improving posture, physiotherapy (if the problem stems from musculoskeletal issues), and, of course, use of NSAIDs when required.
• Dietary components and headaches: Some foods and food components have a reputation for provoking headaches or migraines in certain people. These triggers can differ from one individual to another, and not all individuals will react to the same foods in the same way. Here are various foods/food components that have been reported to induce headaches in some individuals: alcohol (possible mechanisms: dehydration; increased blood flow rushing to the head); caffeine (possible mechanism: When consumed in moderate amounts, caffeine can provide relief from pain, and it is an ingredient in various over-the-counter migraine medications. However, excessive caffeine intake, such as consuming more than two sodas or two cups of coffee daily, can lead to migraine-like symptoms when you reduce your caffeine intake.); nitrites and nitrates (The substances present in processed meats such as bacon, hot dogs, and deli meats could potentially induce a migraine. These substances are employed to preserve the freshness of the meats. Medical professionals believe they could cause the blood vessels in your brain to widen, which could initiate headache discomfort.), and so on. To stop the symptoms associated with these foods, it is best to avoid consuming them.
• Vision problems and headaches: Headaches and vision/eye impairment usually go hand in hand. Strain (being in front of a screen for long periods of time), refractive problems (myopia, astigmatism, and hyperopia), allergic reactions, diseases (increased intraocular pressure, glaucoma, and so on) result in weakening of the eye muscles due to exertion. Most common treatments pertaining to the eye include prescription glasses, antihistamines, eye drops, and surgery (i.e., failure to lower intraocular pressure with medication).
• Infection: Infections from the ear/nose/throat area are common causes of headaches. The treatment will vary depending on the type of microorganism detected. Most commonly, NSAIDs, antibiotics, and decongestant medications are used.
• Medication-induced headache: Medication-induced headaches, alternatively termed medication-overuse headaches or rebound headaches, manifest when specific medications are used excessively or too frequently. These headaches pose a unique challenge since the very drugs intended to alleviate headaches can, in some cases, contribute to their onset. The treatment consists of gradually tapering down the dosage of the medication and using them only in a limited manner.
• Cluster headache: A cluster headache is a type of severe and extremely painful headache that belongs to the group of primary headaches, which means it is not caused by an underlying medical condition. Cluster headaches are known for their recurring pattern of intense, stabbing pain, often described as one of the most excruciating pains a person can experience. Here are some key characteristics and features of cluster headaches: very intense in nature - debilitating; short-lived but intense/sharp and can be centered around the eye, forehead, or temple; as the name explains, it occurs in clusters which can be followed by periods of remission; very difficult to manage. Treatment includes triptan medication, high-flow oxygen, and calcium channel blockers.
• Headaches associated with the nervous system: Any condition resulting in inflammation of the nerves can result in headaches. Here are some common causes: Chronic conditions (i.e., diabetes, constant hypertension can result in atherosclerotic plaque formation and/or vessel damage thus resulting in hemorrhage); dietary deficiencies (vitamin B12, folate induce nerve damage); infections reaching the brain; tumor. Treatment will depend on the cause of the nerve damage.
• ENT-related illnesses and headaches: Patients that experience infections/other problems of the ENT area (tonsillitis, sinus infections, allergic reactions, trauma, and so on) are prone to recurring types of headaches.

Diagnostic procedures of headaches

It's crucial to understand that headaches can stem from a range of factors, and they can be either primary (occurring without an underlying issue) or secondary (linked to an underlying medical problem or injury). Receiving an accurate diagnosis is essential for crafting the most suitable treatment and care strategy tailored to the particular type of headache you're dealing with. If you frequently experience severe headaches, it's wise to seek medical attention to undergo a comprehensive assessment and obtain an accurate diagnosis. Crucial steps that the physician will go through:

• Complete history of the patient: They will ask about the characteristics of your headaches, including the location, intensity, duration, and any associated symptoms. They will also inquire about your overall health, past medical conditions, family history of headaches, and any potential triggers or patterns related to your headaches.
• Physical exam: The healthcare provider may check your blood pressure, perform a neurological examination, and examine your head, neck, and eyes.
• Journaling: Keeping a diary with all the information pertaining to the headaches (duration, possible triggers, and so on) is crucial.
• Imaging tests and blood work: If the condition is unclear, your physician might order imaging to investigate/rule out other more serious conditions (CT scan, MRI). In addition, blood tests can be performed to test for dietary deficiencies and infection.
