Headache (cephalgia): causes, diagnosis and treatment

Causes

Why does my head hurt? Common causes of headaches are:

• neck muscle spasm;
• compression of the vessels of the head and neck;
• compression of the membranes of the brain;
• brain nutritional disorders: insufficient blood supply, narrowing of blood vessels supplying the brain;
• smoking, poisoning with alcohol, drugs, medications;
• stress, sleep disturbance;
• due to neck and head injuries;
• birth injuries;
• anomalies in the development of blood vessels in the neck and head.

Prevention methods

According to statistics, adults often have headaches due to acquired disorders. Common causes are poor diet, stress and lack of rest, and excess weight. Today, many people, including young people, lead a sedentary lifestyle, which also negatively affects the general condition of the body. Doctors at the Clinical Institute of the Brain have several tips on how to provide timely prevention of headaches at home:

• regularly measure blood pressure, especially at the age of 40 years or more;
• perform simple exercises for the neck and head every day, including during the working day;
• consume sufficient amounts of vitamins and microelements;
• give up bad habits, smoking and drinking alcohol, as well as fatty foods high in cholesterol.

If a person has a headache for several days or even weeks, it is worth contacting the Clinical Brain Institute. Doctors will develop an individual program for diagnosing and treating chronic pain. The scheme will include only the necessary informative techniques that will allow you to quickly make an accurate diagnosis and select the most effective course of treatment, including at home.

Primary headaches

Secondary

Secondary headaches can be a sign of other diseases. Most often it is caused by the following diseases:

Causes of headaches at night

Pain in the head at night can occur in a healthy person or be a symptom of various diseases. If they appear once, this may indicate unsuitable sleeping conditions or other external factors. However, chronic pain that worsens at night requires diagnosis and treatment from a specialist. There are a number of diseases and conditions that can be detected during the examination.

Hypertension

High blood pressure is a common cause of headaches day and night. Hypertension occurs when blood pressure increases on the vascular walls. This may be due either to increased vascular tone or to the accumulation of excess fluid in the body.

Hypertension can be identified by the following symptoms:

• acute headaches, which can intensify with a lack of oxygen, after exercise or long rest;
• attacks of nausea, dizziness;
• redness of the facial skin.

In some patients, blood pressure is constantly elevated, but often the disease manifests itself in attacks. Normal values ​​are 120∕80 mm. rt. Art. Their increase to 140∕90 or more can be caused by stress, physical activity, climate change and other factors. To treat chronic hypertension, drugs are used to strengthen and relax the vascular walls, as well as diuretics.

Increased intracranial pressure

Intracranial hypertension is a chronic disease that manifests itself as acute headaches. Pathology manifests itself as the difference between atmospheric pressure and the indicator in the cavities of the skull increases. Here, pressure is exerted by several structures: blood in the vessels of the head, fluid of the cerebral ventricles and brain tissue.

Intracranial hypertension is manifested by characteristic symptoms:

• pain in the head at night and in the morning;
• various sleep disorders;
• disorders of the nervous system;
• deterioration of memory and attention, decreased concentration.

The diagnosis of intracranial hypertension is made based on clinical signs. It is impossible to accurately measure this indicator because it includes several factors. To diagnose its cause, an MRI of the head is prescribed and blood flow in the cerebral vessels is examined. During attacks, brain tissue receives insufficient oxygen and nutrients, which leads to chronic ischemia and increases the risk of stroke.

Histamine disease

Histamine disease (Horton's migraine ) is a chronic disease, the cause of which remains unclear. Excess histamine accumulates in cells and tissues, which causes a typical clinical picture. The patient begins to have a headache at night, and the attacks of pain are acute, but short-lived. Additional symptoms are also identified:

• unilateral headache during sleep;
• lacrimation, swelling of the eyelids;
• swelling of the nasal mucosa, difficulty breathing.

During an attack, dilation of the carotid arteries is determined. However, more often the headaches are short-lived and go away before the doctors arrive. A characteristic sign of the disease is an increase in the clinical picture after histamine injections. Treatment consists of painkillers and steroidal anti-inflammatory drugs.

Poisoning

Intoxication is one of the reasons why you get a headache at night. Poisoning can occur after consuming low-quality foods and alcohol, being bitten by insects, inhaling toxic gases, or coming into contact with chemicals. There is also a distinction between drug poisoning, which is often associated with dosage violations.

Toxins spread through the bloodstream and reach the brain. This leads to tissue ischemia, nerve conduction disturbances, and acute headaches. It is important to provide first aid in case of poisoning in a timely manner. If an antidote is known, it is immediately administered in the required dosage. In other cases, gastric lavage and drip administration of electrolyte solutions are indicated to reduce the concentration of toxins in the blood and prevent dehydration.

Sleep apnea

Obstructive sleep apnea is a chronic pathology in which breathing stops for more than 10 seconds during sleep. It may be associated with the anatomical features of the structure of the tongue and lower jaw, as well as with the patient’s excess weight. Due to the blockage of the oropharynx, air is retained and does not flow through the respiratory tract. The diagnosis can be made based on typical symptoms:

• headache at night and upon waking;
• insomnia, sleep disorders;
• during the day – chronic fatigue, fatigue, deterioration of memory and concentration;
• snoring in your sleep.

Sleep hypopnea is a condition in which breathing does not stop completely, but not enough air enters the lungs. Cells and tissues, including the brain, experience oxygen starvation, which is accompanied by frequent headaches. In addition, patients with sleep apnea and hypopnea are at risk of stroke and chronic diseases of the cardiovascular system.

Other reasons

There are both pathological and physiological causes of night headaches. They are associated with internal or external factors that cause impaired cerebral circulation or intoxication in the absence of acute and chronic diseases of internal organs. So, night headaches can be triggered by the following factors:

• sleeping in a stuffy room, lack of oxygen and high gas pollution;
• drinking alcohol or fatty foods before bedtime;
• lack of physical activity;
• mental or physical fatigue;
• stress, tension.

Even a healthy person can have a headache during sleep. If this happens rarely and is associated with external factors, it is enough to devote time to preventing headaches. However, frequent attacks are not normal and indicate the need for a full examination.

When you can't put off visiting a doctor

1. For an acute headache that suddenly arose and resembles “a blow to the head.” This may be a symptom of subarachnoid hemorrhage. Call an ambulance immediately.
2. The pain intensifies when lying down and goes away half an hour after getting out of bed. This is a sign of impaired outflow of cerebrospinal fluid, increased intracranial pressure, and a tumor.
3. If the headache appears regularly, is intense, is associated with changes in body position and changes with movement.

Treatment

Treatment for headaches depends on their cause.

Some simple methods can reduce the likelihood of headaches:

• frequent breaks at work
• do not sit in hunched or tense positions
• move as often as possible
• drink more water throughout the day
• healthy eating
• avoid headache triggers such as alcohol
• regular eye examination
• wearing lenses prescribed by your eye doctor

Migraines can be more difficult to treat, but a combination of medications and lifestyle changes can often help.

Headaches caused by blood pressure may require lifestyle changes, blood pressure medications, or other treatment.

If a stroke or aneurysm causes a headache, then the person needs emergency help.
