Dizziness may occur for a variety of reasons, from overconsumption of alcohol to inner ear problems. Some causes can be easily treated with medication or at-home exercises. Other causes are more serious and require immediate medical attention. Listed below are some of the most common causes of dizziness.
Electronystagmography
Electronystagmography is a test that assesses eye movements and muscle activity to determine the causes of dizziness and vertigo. The procedure evaluates the vestibular system, which includes the inner ear, the eye muscles, and the nerves that send signals to the brain to interpret movement. Problems in this system can lead to dizziness and nausea, and may require treatment with medicine.
The primary causes of dizziness are peripheral vestibulopathies, psychiatric disorders, and cerebrovascular disease. Brain tumors and cerebrovascular disease are the least common etiologies. A careful physical examination and history are the key to diagnosis. The findings of the physical examination and history are a vital basis for laboratory testing and cardiovascular and neurologic evaluations. While vestibular testing may be useful in diagnosing certain conditions, there is not enough evidence to recommend the test in all cases.
Electronystagmography can also be used for other purposes. It helps doctors diagnose balance problems as well as certain types of vestibular diseases. The test is performed with the aid of video cameras.
Peripheral neuropathy
If you experience symptoms of peripheral neuropathy, you may need to visit a doctor or an orthopedist. Although this disorder can be difficult to treat, lifestyle changes can help alleviate symptoms. Stopping smoking and limiting alcohol intake are good ways to keep your body healthy and reduce your risk of neuropathy. You should also consult your doctor about your health history to determine whether you are at risk for peripheral neuropathy.
A blood test is one way to determine if peripheral neuropathy is causing your symptoms. It can reveal vitamin and mineral imbalances, a thyroid problem, and antibodies to certain viruses or autoimmune diseases. Other tests may include magnetic resonance imaging (MRI) to detect tumors or pinched nerves. Genetic tests may also be recommended.
Symptoms of peripheral neuropathy vary greatly. A comprehensive examination is essential to rule out a definite diagnosis. The doctor will take a medical history including details about your family’s health history, symptoms, and lifestyle. The doctor will also want to know if your family has any history of neurological problems. Generally, a neuropathic condition will progress slowly. There are periods of improvement and plateaus, but many sufferers find their condition continues to worsen over time.
Multiple sclerosis
Dizziness is a common symptom of Multiple Sclerosis (MS). MS-related dizziness can be caused by lesions in the vestibular system, which coordinates visual, spatial, and other data. This system is essential for maintaining proper balance and coordination. In addition, lesions can occur on the brain stem, which connects the inner ear with the brain. In some people, lesions may also affect the cerebellum, which controls balance.
Early detection of MS symptoms is vital, as early treatment can help manage symptoms and slow disease progression. Early symptoms often last for just a few days. However, if they last for more than a few days, they could be indicative of an underlying medical condition. In addition to the symptoms, patients suffering from early signs of MS may experience trouble walking down hallways.
People with MS who are experiencing frequent episodes of dizziness should consult a doctor to find out the cause of their symptoms. The first step is to rule out other causes, such as a vestibular infection. During the evaluation process, a doctor will help determine if MS is the cause of the symptoms and suggest treatment.
Strokes
Dizziness may be one of the first symptoms you experience after having a stroke. The brainstem is responsible for maintaining balance, and a stroke can affect the part of the brain that controls the eye, facial muscles, and vestibular nerves. If you experience dizziness without other stroke symptoms, it is important to seek medical attention immediately.
In adults, dizziness is a common presenting symptom to the emergency room. Although only a small fraction of these cases are associated with dangerous cerebrovascular injury, it is important to be aware of the possibility of stroke, as it often goes undiagnosed. Failure to recognize stroke can lead to poorer patient outcomes.
A stroke may cause dizziness in as many as 10% of patients. It is important to note, however, that dizziness is no guarantee that you have had a stroke. Fortunately, there are several ways to identify a stroke and its symptoms. One way to get a more accurate diagnosis is to have a comprehensive physical examination.
If you are concerned about dizziness, you should make an appointment with a neuro-ophthalmologist. A neuro-ophthalmologist will be able to conduct accurate tests and provide reliable results. A bedside neurologic and oculomotor examination can also identify patients who have a high risk of stroke.
Parkinson’s disease causes dizziness
Dizziness can be a sign of an underlying condition, such as Parkinson’s disease. If you are experiencing dizziness, contact your physician. Your doctor can recommend certain treatments to manage the condition. One such treatment is physical therapy, which can help you control the symptoms of dizziness. A physical therapist can teach you exercises that will help you increase your body’s stability.
Patients with Parkinson’s disease may experience dizziness if they develop degeneration in the cervical-vertebral region. This region contains proprioceptive nerves that coordinate head and eye posture. If the condition affects these pathways, the patient may experience dizziness when moving their head and neck.
Another cause of dizziness in people with PD is orthostatic hypotension, or BPPV. This condition affects the inner ear and can lead to loss of balance. It is most common in older people with PD. The first step in treating it is to make sure that the patient is experiencing orthostatic hypotension.
Another reason patients with PD experience dizziness is because of the medications they take. Orthostatic hypotension is a common symptom of PD, and many medications used for PD make it worse.
TIA
If you feel dizzy or lose consciousness and think you may be having a TIA, you should immediately contact a medical professional. A doctor will perform diagnostic testing and order blood tests. Your doctor may also request a brain scan or MRI. These tests will help determine the location of the dizziness. Other tests may include an electrocardiogram to determine if sleep apnea is the cause. Blood work can also reveal risk factors for stroke.
It is difficult to rule out a stroke in a dizzy patient. Standard clinical care, including the use of MRI and neuroimaging, cannot always detect a stroke. Furthermore, it would be very expensive to scan every patient who presents with symptoms of dizziness. This is why a thorough diagnosis is important.
A TIA can cause dizziness and other symptoms of a stroke. These symptoms usually last for a few minutes or a day. If you think you are having a TIA, see a doctor as soon as possible. This symptom serves as a warning of a stroke and should be taken seriously. In fact, 15 percent of people with a TIA will go on to develop a stroke within 90 days.
