A stroke occurs if the flow of oxygen-rich blood to a portion of the brain is blocked. Without oxygen, brain cells start to die after a few minutes. Sudden bleeding in the brain also can cause a stroke if it damages brain cells. A stroke is a serious medical condition that requires emergency care. A stroke can cause lasting brain damage, long-term disability, or even death. If you think you or someone else is having a stroke, call 911 right away.
What Are the Symptoms of a Stroke?
Vascular disorder includes any condition that affects the circulatory system. As the heart beats, it pumps blood through a system of blood vessels called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body. Arteries carry blood away from the heart while veins return it. Vascular disease ranges from diseases of your arteries, veins, and lymph vessels to blood disorders that affect circulation.
If you have recently experienced a stroke or suffer from a vascular disorder and would like to speak to a doctor about treatment, make an appointment by calling (818) 937-9944.
A migraine headache can cause intense throbbing or a pulsing sensation in one area of the head and is commonly accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can cause significant pain for hours to days and be so severe that all you can think about is finding a dark, quiet place to lie down. Some migraines are preceded or accompanied by sensory warning symptoms (aura), such as flashes of light, blind spots, or tingling in your arm or leg. Medications can help reduce the frequency and severity of migraines.
Migraine headaches are often undiagnosed and untreated. If you regularly experience signs and symptoms of migraine attacks, keep a record of your attacks and how you treated them.
If you suffer from migraines or other headache disorders and would like to speak to a doctor about treatment, make an appointment by calling (818) 937-9944.
The word “dementia” is an umbrella term used to describe a set of symptoms, including impairment in memory, reasoning, judgment, language and other thinking skills. Dementia begins gradually in most cases, worsens over time and significantly impairs a person’s abilities in work, social interactions and relationships. Often, memory loss is one of the first or more-recognizable signs of dementia.
What Are the Symptoms of Dementia?
Diseases that cause progressive damage to the brain and consequently result in dementia include:
People with dementia may have problems with short-term memory, keeping track of a purse or wallet, paying bills, planning and preparing meals, remembering appointments or traveling out of the neighborhood.
If you suffer from dementia and would like to speak to a doctor about treatment, make an appointment by calling (818) 937-9944.
Multiple sclerosis (MS) is a disease of the central nervous system (CNS). The CNS consists of the brain, optic nerves and spinal cord. With MS, areas of the CNS become inflamed, damaging the protective covering (known as “myelin”) that surrounds and insulates the nerves (known as “axons”). In addition to the myelin, over time, the axons and nerve cells (neurons) within the CNS may also become damaged.
The damage to the protective covering and also to the nerves disrupts the smooth flow of nerve impulses. As a result, messages from the brain and spinal cord going to other parts of the body may be delayed and have trouble reaching their destination.
What Are the Symptoms of MS?
While MS has the potential to cause several different symptoms, the specific symptoms each person experiences vary greatly. Medications are available to treat many MS symptoms. These may include over-the-counter drugs as well as prescribed medications. Diet and exercise may also be helpful with managing certain symptoms. All treatments or changes in diet or exercise should only be done under the guidance of a qualified physician.
If you suffer from MS and would like to speak to a doctor, make an appointment by calling (818) 937-9944.
Neuropathy is the term used to describe a problem with the nerves, usually the ‘peripheral nerves’ as opposed to the ‘central nervous system’ (the brain and spinal cord).
What Are the Symptoms of Neuropathy?
If you suffer from neuropathy and would like to speak to a doctor about possible treatment, make an appointment by calling (818) 937-9944.
Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death. Half of all TBIs are from motor vehicle accidents.
What Are the Symptoms of Traumatic Brain Injury?
Symptoms of a TBI may not appear until days or weeks following the injury. A concussion is one example. It can cause a headache or neck pain, nausea, ringing in the ears, dizziness, insomnia, irritability, and fatigue. People with a moderate or severe TBI may have those, plus other symptoms:
A neurologist can perform an exam and imaging tests to assess TBI. Serious traumatic brain injuries need emergency treatment.
If you suffer from TBI and would like to speak to a doctor about possible treatment, make an appointment by calling (818) 937-9944.
A sleep disorder is a medical disorder of the sleep patterns of a person. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Disruptions in sleep can be caused by a variety of issues, from teeth grinding (bruxism) to night terrors. When a person suffers from difficulty falling asleep and/or staying asleep with no obvious cause, it is referred to as insomnia.
Some common sleep disorders include sleep apnea (stops in breathing during sleep), narcolepsy and hypersomnia (excessive sleepiness at inappropriate times), cataplexy (sudden and transient loss of muscle tone while awake), and sleeping sickness (disruption of sleep cycle due to infection). Other disorders include sleepwalking, night terrors and bed wetting. Untreated sleep disorders especially obstructive sleep apnea can lead to serious health hazards. Sleep related disorders are usually diagnosed on a polysomnogram or sleep study.
If you suffer from sleep disorders and would like to speak to a doctor about possible treatment, make an appointment by calling (818) 937-9944.
Neuromuscular diseases are acquired or inherited (genetic) conditions that affect some part of the neuromuscular system such as:
More than a million people in the United States are affected by some form of neuromuscular disease, and about 40 percent of them are under age 18. All neuromuscular diseases are progressive in nature, and all result in muscle weakness and fatigue. Some diseases are present at birth, some manifest in childhood, and others have an adult onset. The disease may be passed down through family genetic lines, and in some cases the affected individual may have an affected sibling, parent or other relative. At other times there is no family history and the disease is the result of a spontaneous genetic mutation, an abnormal immune response or an unknown (idiopathic) cause.
If you suffer from nerve and muscle disorders and would like to speak to a doctor about possible treatment, make an appointment by calling (818) 937-9944.
A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain. Seizures occur when a person’s body shakes rapidly and uncontrollably. During seizures, the person’s muscles contract and relax repeatedly. There are many different types of seizures. Some have mild symptoms without shaking.
What Are the Symptoms of a Seizure Disorder?
If you suffer from seizure disorders and would like to speak to a doctor about possible treatment, make an appointment by calling (818) 937-9944.
Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs, sounds or numerical values that a specialist, such as Dr. Harutunian interprets. An EMG uses tiny devices called electrodes to transmit or detect electrical signals.
During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission. An EMG is conducted if you have signs or symptoms that may indicate a nerve or muscle disorder.
What Are the Symptoms Requiring an EMG?
EMG results are often necessary to help diagnose or rule out a number of conditions such as:
In addition to his training as a Neurologist, Dr. Harutunian is also fellowship trained at the Keck Hospital of USC and board certified specifically in electrodiagnostic medicine, which includes EMG studies. If you suffer from any of the symptoms described above and would like to speak to a doctor to see if an EMG will help with the diagnosis of your symptoms, make an appointment by calling (818) 937-9944.
A nerve conduction study (NCS) is a measurement of the speed of conduction of an electrical impulse through a nerve. NCS can determine nerve damage and destruction. During the test, the nerve is stimulated, usually with surface electrode patches attached to the skin. Two electrodes are placed on the skin over the nerve. One electrode stimulates the nerve with a very mild electrical impulse and the other electrode records it. The resulting electrical activity is recorded by another electrode. This is repeated for each nerve being tested. The nerve conduction velocity (speed) is then calculated by measuring the distance between electrodes and the time it takes for electrical impulses to travel between electrodes.
A related procedure that may be performed is electromyography (EMG) (see description in section above). An EMG measures the electrical activity in muscles and is often performed at the same time as NCS. Both procedures help to detect the presence, location, and extent of diseases that damage the nerves and muscles.
In addition to his training as a Neurologist, Dr. Harutunian is also fellowship trained at the Keck Hospital of USC and board certified specifically in electrodiagnostic medicine, which includes EMG and NCS studies. If you would like to speak to a doctor to see if a nerve conduction study will help with the diagnosis of your symptoms, make an appointment by calling (818) 937-9944.
An EEG is a test that detects electrical activity in your brain using small, flat metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you are asleep. This activity shows up as wavy lines on an EEG recording. An EEG is one of the main diagnostic tests for epilepsy. An EEG may also play a role in diagnosing other brain disorders.
In addition to his training as a Neurologist, Dr. Harutunian is also fellowship trained at the Keck Hospital of USC and board certified specifically in electrodiagnostic medicine, which includes EEG studies for the diagnosis of epilepsy and other central nervous system disorders. If you would like to speak to a doctor to see if a nerve conduction study will help with the diagnosis of your symptoms, make an appointment by calling (818) 937-9944.
