Some issues Dr. Gerrard F.A. Ferrer, DO can help you with:

Facial Paralysis

Facial paralysis is an inability to move the muscles in the face. It often affects only one side, and it can happen quite suddenly. Facial paralysis may make one's face feel frozen or numb.

Facial paralysis can happen when there is inflammation or damage to either the part of the brain that controls the facial muscles or the nerve that carries signals from the brain to the face. Some common causes include:

  • Stroke, which can affect the part of the brain controlling the face and prevent those muscles from working
  • Bell's palsy, an inflammation of the main facial nerve
  • Lyme disease
  • Birth trauma or difficult birth, which can cause facial paralysis in babies (usually temporary)
  • Head trauma in which nerves are damaged

Facial paralysis is a frustrating and frightening experience, but many cases are temporary and go away on their own. Even with more difficult cases, there are treatment options available, including rehabilitation, pain management, and surgery.

Headache

Headaches are dull or sharp pains that occur in regions of the head and face. Headaches occur in many different forms and vary in location, severity, and duration. They are not necessarily a sign of an underlying illness and often resolve on their own. However, headaches can present significant day-to-day discomfort. The most common forms of headaches include:

  • Migraines: one of the most prevalent types of headache, migraines typically last from two hours to three days, causing a throbbing pain on one side of the head. Nausea, sensitivity to bright lights, fatigue, and blurred vision all may accompany migraines. While migraines have no known cure, medications and lifestyle modifications may ease symptoms. Avoiding behaviors that may trigger migraines such as lack of sleep or loud, repetitive noises can improve headaches.
  • Tension headaches: also known as stress headaches, these headaches are characterized by pain in the upper top part of the head and behind the eyes. Tension headaches are common and have no exact cause; however, certain practices may increase the likelihood of developing them. For example, wearing one's hair up in a tight hairstyle or wearing a restrictive hat can put pressure on the scalp, leading to a tension headache. Other causes of tension headaches may include alcohol or nicotine use, caffeine, teeth grinding, stress, overexertion, and eye strain. Some people find posture improvement, alternating sleeping positions, and neck exercise can alleviate tension headaches. Over-the-counter pain relievers such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve) may also reduce tension-headache pain.
  • Sinus headaches: this type of headache causes pain in the sinuses, but may progress to pain and pressure in the eyes, forehead, and cheeks. These headaches are often accompanied by nasal congestion, fatigue, and ache in the upper teeth and may or may not be caused by sinus infections or sinusitis (sinus inflammation). Some sinus headaches are allergic headaches, which arise from allergic triggers such as seasonal allergies (pollen allergies) or hay fever, causing sinus pressure and facial pain. Other symptoms of allergic headaches include nasal congestion, irritated or watery eyes, runny nose, and sneezing. Allergic headaches may be treated with antihistamine medications such as cetirizine (Zyrtec). Allergic headaches are common during pollen season, which is usually around springtime.
  • Cluster headaches: these headaches occur suddenly and cause stabbing, sharp pain from one eye down to the one side of the neck. They are often referred to as the most aggravating and painful type of headaches. Other symptoms of cluster headaches include nasal congestion, droopy eyelid, and enlarged pupil on one side of the face. In the past, it was widely believed that cluster headaches were caused by a bevy or "cluster" of multiple types of headaches, such as a combination of an allergic headache and a tension headache. Medical experts now recognize that cluster headaches are a separate and unique form of headache. Cluster headaches last for around twenty minutes to two hours. They may recur throughout the period of a day or several weeks, but usually dissipate within a month. Treatment for cluster headaches includes over-the-counter pain medications such as ibuprofen (Advil, Motren) and naproxen sodium (Aleve). Prescription Prednisone can help with swelling and Verapamil may reduce pain by relaxing the blood vessels.

Living with headaches is challenging; headaches can prevent people from fully enjoying life. Medical treatment and care in avoiding certain triggers can help those with headaches begin to feel normal once again.

Stroke

A stroke is a medical emergency that occurs when a blood vessel supplying oxygen and nutrients to the brain is ruptured or blocked. The brain cannot function without a steady supply of oxygen and nutrients, so when the blood supply to the brain is interrupted, even for a brief moment, brain cells begin to die. When a sufficient number of brain cells die, the brain itself can no longer function, meaning that strokes are very dangerous. Strokes can result in impaired movement, speech, cognitive ability, the impairment of important physical functions, and even death.

Anyone can have a stroke, regardless of age and health. Strokes are known to happen at random. However, certain conditions and behaviors can increase one's risk of stroke over time.

Risk factors for stroke include:

  • Heart disease
  • Older age
  • Smoking
  • Diabetes
  • High blood pressure
  • High blood cholesterol and lipids

There are two main types of stroke: ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs more commonly and is when a blood vessel in the brain becomes blocked. Blockages are caused by blood clots and built-up plaque (deposits of fat and cholesterol), which leads to atherosclerosis, a condition where the blood vessels narrow and harden. The resultant restricted blood flow may lead to an ischemic stroke by blocking essential oxygen to the brain, causing the heart to exert more effort to pump blood.

Hemorrhagic stroke occurs when a blood vessel in or around the brain ruptures. The burst vessel leaks blood into surrounding brain tissue, causing irreparable brain damage.

Hemorrhagic strokes are less common and may occur from head injuries, brain aneurysms, brain tumors, and bleeding disorders, amongst other conditions.

Both ischemic and hemorrhagic strokes require immediate medical treatment. Medical intervention can prevent severe and life-threatening brain damage. Signs of stroke include:

-Disorientation or confusion

-Difficulty speaking

-Difficulty walking

-Impaired vision

-Weakness in the face, legs, or arms

-Severe headaches

When someone suspected of having a stroke reaches the hospital, the patient will usually receive a CT or other scan that provides an image of the brain. The scan results can reveal clotted or leaking blood in the brain. Physical exams, neurological exams, and blood tests may also be used to check for blood clotting and sugar. Treatment begins generally immediately if a stroke is detected.

Medical treatment for ischemic strokes includes a thrombolytic medicine which breaks up and disperses blood clots. This medicine can greatly improve stroke recovery and long-term health. However, the thrombolytic medicine must be administered as soon as possible to achieve these results. Other treatments for ischemic strokes are blood thinners and thrombectomy, a surgical procedure to remove a blood clot in the brain. Thrombectomy is performed by inserting a catheter (thin needle) into the artery to reach the blood clot and mechanically remove it. With the clot removed, normal blood flow to the brain resumes. Thrombectomy is typically performed at most six hours after a patient shows signs of a stroke.

Hemorrhagic strokes are treated with blood-saving medication and surgery. For a hemorrhagic stroke caused by the rupture of an aneurysm (blood vessel bulges), surgery to stem the bleeding aneurysm and vessel may be used. One surgical technique is stent-assisted coiling, which adds a stent (small wire-meshed tube) into the blood vessel to block the leaking opening of the aneurysm. A non-surgical procedure is endovascular coiling, where a catheter (thin, hollow needle) places a platinum wire coil at the spot of the aneurysm. The coil blocks bleeding and prevents the aneurysm from continuing to leak blood. These procedures are usually combined with blood-thickening medications. Blood transfusions may be administered if substantial blood loss has occurred.

Since stroke patients may have lost some essential functions while the blood flow to their brains was obstructed, both ischemic stroke and hemorrhage stroke patients may receive post-stroke rehabilitation to rebuild their physical and mental abilities. Some restorative treatments include occupational, physical, and speech therapy. Patients may also receive care from neurologists, who can assist patients in recovering certain brain functions and cognitive abilities, and rehabilitation psychologists, who may help patients with their emotional, behavioral, and cognitive recovery. Some stroke patients require lengthy rehabilitation and may never fully regain function, while others may recover more quickly. While the fastest recovery improvements are usually seen in the first three or four months, stroke rehabilitation can last for years.

If someone begins to show signs of stroke, contact emergency services and call 9-1-1 immediately since blood flow must be restored as soon as possible to help avoid significant brain damage. If an ambulance takes the person to the hospital, paramedics can initiate stroke treatment as soon as the patient enters the ambulance, allowing for more prompt medical intervention and care.
