Dr. Ali Ghahary, a family physician in Burnaby, British Columbia, treats patients at all stages of life. Having previously served in a practice with a high percentage of elderly patients, Dr. Ali Ghahary draws on an in-depth knowledge of Alzheimer’s disease and other conditions of advanced age.

In its early stages, Alzheimer’s disease may closely resemble the natural forgetfulness of later life, though certain key differences are noticeable. Many older individuals report trouble forgetting appointments or the names of new acquaintances, but this manifests differently in a patient with early-stage Alzheimer’s. These patients forget new information often and frequently need to have the same information repeated multiple times.

Many older people forget the day of the week or the month, but they are able to recall this information after thinking on it for a moment. Patients with Alzheimer’s, by contrast, may lose track not only of dates but also of their sense of time. They may not be able to understand events that are not happening immediately, and they may forget the current season and even lose track of their surroundings.

Similarly, although it is normal for an older person to misplace an item occasionally, patients with Alzheimer’s may not be able to retrace their earlier steps and find where they may have laid down the item. They may accuse others of stealing the item, particularly if they are experiencing the personality changes or increased moodiness that often characterizes the disease. These social challenges, combined with a new inability to follow conversations, may make patients with Alzheimer’s disease more withdrawn, as well.

Common Food Allergies and How to Avoid Them

peanut-999921_1280Food allergies have become an increasing health concern in Canada over the years, with as many as 2.5 Canadians suffering from at least 1 common food allergy. The highest incidence of food allergies is found in children.

Below is a look at some of the most common food allergens according to Health Canada:

Peanuts:
The most common food allergy, especially in children, is a peanut allergy (affecting 2 in 100.) Peanut allergies have become so severe that some schools have banned peanuts or products containing peanuts all together, and is considered a “priority” allergen that must be listed on all ingredient labels if manufactured in a facility that also produces products containing nuts. As a result, more and more companies and begun introducing nut and/or peanut-free products that are specifically advertised towards school-aged children such as cookies, crackers and chocolate. Other nut allergens include tree nuts; these include hazelnuts, cashews, macadamia nuts, pecans, pine nuts, walnuts and pistachios.

Milk:
This includes all dairy products such as cheese, yogurt, and ice-cream. Many products contain milk, even in powdered form. It can be found in baked goods, coffee, soup mix, and even tofu.

Seafood:
Clams, scallops, shrimp, and lobster are all common seafood allergies. However, it is important to note that individuals with a seafood allergy are often able to eat certain types of seafood, while having to avoid other types all together. Seafood reactions can be severe, as one does not necessarily need to eat it in order to react to it. The smell of fish is enough to trigger an allergic reaction in some individuals. Seafood can also commonly (but oftentimes unknowingly) be found in salad dressings and sauces.

Soy:
Soy is another common allergen, but one that is not always easy to detect without carefully reading labeling. It can be found in everything from certain foods such as tofu, to candy, chewing gum, and even baby formula.

Sulphites:
An additive that is commonly used to preserve the shelf life of fruits, vegetables, and certain packaged foods. While sulphites are usually safe, they can still trigger allergic reactions and asthma in sulphite-sensitive individuals. If you have a sulphite allergy or sensitivity, it is best to avoid packaged foods and ensure you thoroughly wash all fruits and vegetables before consumption.

When we think of an allergic reaction, we often think of hives, swelling, or a rash. Anaphylaxis (usually resulting in trouble breathing or swallowing, or other respiratory distress sich as coughing, wheezing ad chest pain/tightness) is another common but serious allergic reaction that can be life-threatening, requiring individuals to carry an Epinephrine auto-injector (EpiPen) with them at all times, something that is easily prescribed by family physicians like Dr. Ali Ghahary. Other signs of an allergy include nausea, vomiting, stomach cramps, diarrhea, dizziness and headache.

It is important to know that one does not need to ingest a large amount of an allergen in order to develop an allergic reaction, as it only takes a trace amount, so to avoid allergic reactions you should always ensure that you take special precautions. When buying food you should always read the ingredients on the packaging, and when dining out you should forewarn your server so that food can be prepared separate from any potential allergens. Proper hand washing and utensil cleaning is also of the utmost importance when it comes to avoiding food allergies and possible cross-contamination.

Concussions: Risks and Prevention

With thousands of children and teenagers now back to school and also partaking in after-school activities, health professionals in Canada, like Dr. Ali Ghahary, will begin to see contact sport-related injuries on the rise such as sprains, bone fractures and concussions.

concussionA concussion occurs when the brain impacts the inside of the skull, usually the result of a direct blow to the head, and causes damage that ultimately changes how your brain cells function.

While concussions are common among athletes and school-aged children, kids and adolescents are also at higher risk of developing a concussion due to the fact that their brains are still growing. Symptoms of conclusions can be physiological (including headaches, dizziness and nausea, cognitive (including lack of concentration, memory loss and slurred speech), as well as emotional (depression and anxiety.) As concussions can have serious and sometimes life-altering effects, it is important that these symptoms are taken seriously and treated immediately. It is also important to watch out for late signs of a concussion, as symptoms can take as long as hours, days, or even weeks to develop. If left untreated, a concussion can lead to a traumatic brain injury (500 out of every 100,000 Canadians are diagnosed with a TBI each year), and can even be fatal.

Children are not the only age group at high-risk of developing concussions, however. Seniors are also susceptible to developing concussions, usually the result of a fall, something that is quite common with age. Studies have also shown that seniors with concussions had a greater risk of developing Alzheimer’s disease as opposed to those who have not had any previous head injuries. Seniors that do develop a concussion may require hospitalization and long-term rehabilitative care depending on the severity of the injury.

In order to prevent a concussion, one should always ensure that they are taking appropriate steps to reduce that risk. These steps include wearing the proper headgear and padding during sports, wearing appropriate footwear, wearing a seatbelt while in a vehicle, and keeping your home safe by moving any clutter and keeping dark spaces well lit. Regular, low-impact exercise in older individuals will also help to strengthen the bones and muscles, improve balance, and decrease the risk of falls.

Strep Throat Symptoms, Diagnosis and Treatment

Strep throat is a bacterial infection that belongs to a class known as Group A Streptococcus (GAS), causing pain and inflammation in the throat. In Canada it accounts for up to 15% of sore throats in adults, and up to 30% of sore throats in children, and is one of the dominant complaints that bring individuals in to see Canadian physicians like Dr. Ali Ghahary. While strep throat commonly materializes in peak seasons such as late winter and early spring, it can also occur any time of the year.

Streptococci bacteria can be found everywhere. Individuals can carry it on their skin and in their throat, and it is passed around similarly to that of a viral infection – by coughing, sneezing, coming into contact with mucus or saliva, and touching others. Symptoms of strep throat include fever (higher than 38 degrees Celsius), chills, sweating, nausea, vomiting, swollen lymph nodes, and headache. Strep throat is typically diagnosed by the appearance of the throat (white patches will usually appear around the tonsils in addition to them looking red and inflamed), or by a throat swab, which is sent to a lab for further testing. Commonly, children with strep throat may also develop middle-ear infections, which can be chronic and reoccurring. In rare cases, one may develop meningitis or scarlet fever. Such complications typically do not develop until 1 to 6 weeks after the strep infection. In order to prevent strep throat, you should always cover your mouth when coughing or sneezing and wash your hands frequently.

lozenge-462867_1280While 90% of sore throats typically get better on their own and can be relieved with things like lozenges, tea and honey, antibiotics will often be prescribed in confirmed diagnoses of strep throat for a period of 5 to 10 days, with Penicillin being the common choice amongst physicians, usually available in oral tablets/capsules or liquid suspension. If you have any known allergies to medications, it is important you let your doctor and pharmacist know so that an alternative medication can be prescribed – these alternative options include Erythromycin, Cephalexin, and Azithromycin. It is always important to finish your prescription, even if symptoms are no longer present. Failure to finish a prescription can result in symptoms returning and worsening. While taking antibiotics you should eat yogurt that contains Lactobacillus Acidophilus, as it will help restore the good bacteria to your digestive tract.
