Causes of New Daily Persistent Headache (NDPH)
New Daily Persistent Headache (NDPH) is a chronic headache disorder that is characterized by the sudden onset of daily headaches that persist for more than three months. While the exact causes of NDPH are not fully understood, several factors have been identified as potential contributors.
Infection
In some cases, NDPH may be triggered by an infection, such as a viral or bacterial infection. The infection can cause inflammation in the brain or spinal cord, which can lead to headaches.
Head Trauma
Head trauma, such as a concussion or head injury, can also trigger NDPH. The trauma can cause damage to the brain or nerves, which can lead to chronic headaches.
Medication Overuse
Overuse of headache medications, such as triptans or opioids, can lead to the development of NDPH. This is known as medication overuse headache or rebound headache.
Genetics
There may be a genetic component to NDPH. Studies have found that people with a family history of migraines or other types of headaches may be more likely to develop NDPH.
Hormones
Hormonal changes, such as those that occur during puberty, pregnancy, or menopause, can trigger NDPH. Women are more likely than men to develop NDPH.
Stress
Stress is a common trigger for many types of headaches, including NDPH. High levels of stress can cause tension in the muscles of the head and neck, leading to headaches.
Sleep Disorders
Sleep disorders, such as sleep apnea or insomnia, can also trigger NDPH. These disorders can disrupt the normal sleep cycle and lead to headaches.
Other Medical Conditions
NDPH can also be associated with other medical conditions, such as autoimmune diseases, thyroid disorders, or brain tumors. These conditions can cause inflammation or pressure in the brain, leading to headaches.
The causes of New Daily Persistent Headache are multifactorial and may include infection, head trauma, medication overuse, genetics, hormones, stress, sleep disorders, and other medical conditions.
Symptoms of New Daily Persistent Headache
New Daily Persistent Headache (NDPH) is a chronic headache disorder that is characterized by the sudden onset of daily headaches that persist for more than three months. The symptoms of NDPH can vary from person to person, but there are some common signs and symptoms that may be present.
1.) Headache: The most common symptom of NDPH is a persistent headache that occurs daily and lasts for more than three months. The headache can be mild to severe in intensity and may feel like a pressure or tightness in the head. The location of the headache can vary, but it often affects both sides of the head and can be felt in the forehead, temples, or back of the head.
2.) Tension Headache: NDPH is often associated with tension-type headaches. These headaches are characterized by a constant, dull ache that feels like a tight band around the head. The pain may be mild to moderate in intensity and can be felt in the forehead, temples, or back of the head.
3.) Migraine Headache: Some people with NDPH may also experience migraines. Migraines are characterized by a pulsing or throbbing pain on one side of the head that can be accompanied by other symptoms such as nausea, vomiting, and sensitivity to light and sound.
4.) Anxiety and Depression: NDPH can be associated with anxiety and depression. The constant pain and disruption to daily life can lead to feelings of anxiety and depression. These symptoms may require additional treatment, such as therapy or medication.
5.) Sleep Disturbances: People with NDPH may experience sleep disturbances, such as insomnia or sleep apnea. These sleep disturbances can worsen the headache symptoms and may require treatment.
6.) Fatigue: Fatigue is a common symptom of NDPH. The constant pain and disruption to daily life can lead to feelings of exhaustion and fatigue.
7.) Sensitivity to Light and Sound: Some people with NDPH may experience sensitivity to light and sound. This sensitivity can worsen headache symptoms and may require management strategies such as wearing sunglasses or earplugs.
8.) Cognitive Impairment: NDPH can also cause cognitive impairment, such as difficulty with memory and concentration. This can be especially problematic for people who need to perform cognitive tasks for work or school.
It is essential for people with NDPH to work closely with their healthcare provider to develop a comprehensive treatment plan that addresses their unique symptoms and needs.
Complications of New Daily Persistent Headache (NDPH)
Although New Daily Persistent Headache (NDPH) is not life-threatening, it can cause complications that require medical attention.
Medication Overuse Headache
One of the most significant complications of NDPH is medication overuse headache (MOH). MOH occurs when a person overuses pain medications to manage their headaches. Over time, the medications can cause rebound headaches that are more severe and frequent than the original headaches. MOH can be challenging to treat and may require a medication tapering program to reduce the risk of rebound headaches.
Depression and Anxiety
NDPH can cause depression and anxiety, which can worsen headache symptoms. The constant pain and disruption to daily life can lead to feelings of hopelessness, sadness, and anxiety. These symptoms may require additional treatment, such as therapy or medication.
Sleep Disorders
NDPH can cause sleep disturbances such as insomnia, sleep apnea, or restless leg syndrome. These sleep disorders can worsen headache symptoms and may require management strategies such as lifestyle modifications, medication, or specialized therapies.
Reduced Quality of Life
NDPH can significantly impact a person's quality of life. The constant pain and disruption to daily life can make it difficult to work, socialize, or participate in activities they enjoy. NDPH can lead to feelings of isolation, frustration, and sadness.
Cognitive Impairment
NDPH can cause cognitive impairment, such as difficulty with memory and concentration. This can be especially problematic for people who need to perform cognitive tasks for work or school.
Financial Burden
NDPH can be expensive to manage. The cost of medications, doctor visits, and diagnostic tests can add up over time, leading to financial stress.
Family and Social Relationships
NDPH can strain family and social relationships. The constant pain and disruption to daily life can make it difficult to maintain social connections or participate in family activities. NDPH can lead to feelings of guilt or frustration, which can strain relationships.
Diagnosis of New Daily Persistent Headache (NDPH)
It is a challenging condition to diagnose New Daily Persistent Headaches (NDPH), and healthcare providers must rule out other potential causes of headaches before confirming an NDPH diagnosis.
Medical History and Physical Exam
The first step in diagnosing NDPH is a thorough medical history and physical exam. The healthcare provider will ask about the onset and characteristics of the headache, including the location, severity, and duration. They will also ask about any other symptoms, such as nausea, vomiting, sensitivity to light or sound, or visual disturbances. The healthcare provider will perform a physical exam, including a neurological exam, to rule out other potential causes of the headache.
Diagnostic Tests
The healthcare provider may order diagnostic tests to rule out other potential causes of the headache. These tests may include:
A.) Imaging tests: Imaging tests such as a CT scan or MRI can help identify structural abnormalities, such as brain tumors or blood vessel malformations that may be causing the headaches.
B.) Blood tests: Blood tests may be ordered to rule out underlying medical conditions such as infections or autoimmune disorders.
C.) Lumbar puncture: A lumbar puncture may be performed to rule out conditions such as meningitis or encephalitis.
Diagnostic Criteria
The International Classification of Headache Disorders, 3rd edition (ICHD-3) provides diagnostic criteria for NDPH. The criteria include:
1.) Headache that is present for more than 15 days per month for at least three months.
2.) The headache must be continuous and unremitting from onset.
3.) The headache must not be attributed to another disorder.
4.) The headache must not be better accounted for by another primary headache disorder.
5.) The headache must not be caused by medication overuse.
The healthcare provider will use the diagnostic criteria and the results of the medical history, physical exam, and diagnostic tests to confirm an NDPH diagnosis.
Treatment of New Daily Persistent Headache (NDPH)
There is no cure for New Daily Persistent Headache, and treatment is focused on managing symptoms. The management of NDPH can be challenging, and a multidisciplinary approach may be necessary.
Medications
Medications are a cornerstone of NDPH management. The goal of medication management is to prevent or reduce the frequency and severity of headaches. Medications used for NDPH include:
A.) Preventive medications
Preventive medications are used to reduce the frequency and intensity of NDPH. These medications are taken daily and work by regulating the chemical imbalances in the brain that cause headaches. The choice of medication depends on the patient's medical history, medication tolerance, and comorbid conditions.
Commonly used preventive medications for NDPH include:
1.) Tricyclic antidepressants: These medications, such as amitriptyline, nortriptyline, or imipramine, work by regulating the levels of neurotransmitters in the brain that are involved in pain perception.
2.) Antiepileptic drugs: Antiepileptic drugs such as topiramate, valproic acid, or gabapentin can help reduce the frequency and intensity of headaches by regulating the activity of brain cells that are involved in pain perception.
3.) Beta-blockers: Beta-blockers, such as propranolol or timolol, reduce the frequency and intensity of headaches by reducing the blood flow to the brain.
B.) Abortive medications
Abortive medications are used to stop a headache once it has started. These medications work by reducing inflammation, constricting blood vessels, or blocking pain signals to the brain.
Commonly used abortive medications for NDPH include:
1.) Triptans: Triptans, such as sumatriptan, rizatriptan, or zolmitriptan, work by constricting the blood vessels in the brain, reducing inflammation, and blocking pain signals.
2.) Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen or naproxen, reduce inflammation and block pain signals.
3.) Acetaminophen: Acetaminophen works by blocking pain signals in the brain.
C.) Medication to manage comorbid conditions
Comorbid conditions such as depression, anxiety, or sleep disorders can worsen NDPH. Medications used to manage these conditions can also help reduce the frequency and intensity of headaches.
Examples of these medications include:
1.) Selective serotonin reuptake inhibitors (SSRIs): SSRIs such as sertraline, fluoxetine, or paroxetine are used to treat depression, anxiety, and some other conditions. These medications work by regulating the levels of serotonin in the brain, which is involved in mood regulation and pain perception.
2.) Benzodiazepines: Benzodiazepines such as lorazepam, diazepam, or clonazepam are used to treat anxiety and some other conditions. These medications work by regulating the activity of brain cells that are involved in mood regulation and pain perception.
Preventive medications, abortive medications, and medications to manage comorbid conditions are all important components of NDPH management. The choice of medication depends on the patient's medical history, medication tolerance, and comorbid conditions.
Lifestyle Modifications
Lifestyle modifications may help reduce the frequency and severity of NDPH. Examples of lifestyle modifications include:
1.) Stress management: Stress is a common trigger for NDPH. Stress management techniques such as meditation, deep breathing, or yoga may be helpful.
2.) Exercise: Regular exercise has been shown to reduce the frequency and severity of headaches. However, patients should be cautious and consult their healthcare provider before starting an exercise program.
3.) Dietary changes: Certain foods may trigger NDPH in some patients. Keeping a food diary and avoiding trigger foods may be helpful.
Complementary Therapies
Complementary therapies may be used in conjunction with medications and lifestyle modifications to manage NDPH. Examples of complementary therapies include:
1.) Acupuncture: Acupuncture may be helpful in reducing the frequency and severity of headaches.
2.) Massage therapy: Massage therapy may help reduce muscle tension and stress, which can trigger headaches.
3.) Cognitive-behavioral therapy (CBT): CBT may help patients identify and change negative thought patterns and behaviors that may contribute to NDPH.

Multidisciplinary Approach
NDPH management may require a multidisciplinary approach. In addition to medication management, patients may benefit from a consultation with specialists such as neurologists, pain management specialists, or psychologists. A multidisciplinary approach may also involve physical therapy or occupational therapy.
Prevention of New Daily Persistent Headache
There is no known way to prevent NDPH, but there are steps a person can take to reduce the risk of developing chronic headaches. These steps include:
1.) Managing stress: Stress can be a trigger for headaches, so finding ways to manage stress, such as exercise, meditation, or therapy, can be helpful.
2.) Maintaining a healthy lifestyle: Eating a healthy diet, getting regular exercise, and getting enough sleep can help prevent headaches.
3.) Avoiding Triggers: Identifying and avoiding triggers, such as certain foods, changes in sleep patterns, or certain environmental factors, can help prevent headaches.
Prognosis of New Daily Persistent Headache (NDPH)
The prognosis of New Daily Persistent Headache (NDPH) varies widely among individuals. Some individuals may experience a complete resolution of their symptoms, while others may continue to experience chronic headaches. The likelihood of a positive prognosis is influenced by various factors such as the age of onset, comorbid conditions, and response to treatment.
Age of onset
The age of onset is an important factor in determining the prognosis of NDPH. Studies have shown that NDPH has a better prognosis in children and adolescents compared to adults. Children and adolescents are more likely to experience complete resolution of their symptoms within months of onset, while adults are more likely to experience chronic headaches.
Comorbid conditions
Comorbid conditions such as depression, anxiety, or sleep disorders can worsen NDPH and affect its prognosis. Effective management of comorbid conditions can help improve the prognosis of NDPH. Medications used to manage these conditions can also help reduce the frequency and intensity of headaches.
Response to treatment
The response to treatment is an important factor in determining the prognosis of NDPH. Effective treatment strategies can help reduce the frequency and intensity of headaches and improve quality of life. However, some individuals may not respond to treatment or may experience side effects from medications, which can affect the prognosis.
Overall, the prognosis of NDPH is highly variable and dependent on individual factors. While some individuals may experience complete resolution of symptoms, others may continue to experience chronic headaches. Effective management of comorbid conditions and response to treatment are important factors that can influence the prognosis of NDPH. Ongoing communication between the patient and healthcare provider is important in adjusting treatment strategies and optimizing outcomes.
