Who can I seek help from for brain fog?

Strictly speaking, brain fog is not a medical condition itself, but rather a symptom of other medical conditions. It is essentially a type of cognitive dysfunction involving memory problems, lack of mental clarity, poor concentration and/or inability to focus. “Brain fog” can make you feel like you are sleepwalking through life. People with this symptom often report feeling tired, difficulty focusing, forgetfulness, or have hazy thought processes. With brain fog, even simple tasks can become a challenge. When you can’t concentrate, mental tasks can feel like a moving target.

Is it possible to be allergic to uncooked oats while not being allergic to cooked oats? (photo)

Sensitivity or allergy to oats is uncommon. People with these conditions have an immune system reaction to avenin, a protein found in oats. The cause of a food-related allergic reaction is an overly sensitive immune system to one or more of the proteins in the oatmeal. The immune system identifies the proteins as dangerous substances and a threat to the body and reacts by attacking the proteins. Immunoglobulin E antibodies trigger a chemical reaction throughout the body, causing white blood cells to produce histamine.

What could numbness in my left ear and adjoining neck pain, when tilting my head too long mean?

One possibility is that of cervical spondylosis. It will be pertinent to seek treatment from a medical professional like your general practitioner, who can order an X ray for you. Cervical spondylosis is a general term for age-related wear and tear affecting the spinal disks in the neck. As the disks dehydrate and shrink, signs of osteoarthritis develop, including bony projections along the edges of bones (bone spurs). Cervical spondylosis is very common and worsens with age. For most people, cervical spondylosis causes no symptoms.

Should I be concerned with dry, peeling foreskin next to the glands of my penis?

Thank you for your interest in such a commonly encountered problem at the clinic. Quite a number of potential causes for dry skin on penis and penis skin peeling came to my mind. 1.) Dry, unlubricated sexual acts, including masturbation or intercourse, can cause enough friction to irritate the skin of the penis. Irritation of the skin of the penis can culminate in itching, flaking, and peeling of the skin. Opt for a water-based lubricant if you have sensitive skin. 2.) Wearing overly tight pants or pants without underwear can also cause irritation from friction.

As a first-time parent, is there anything I should take note of when managing a child with ADHD

Hi there, What is ADHD? ADHD is a neurobiological disorder that affects between five and seven percent of children and between one and three percent of adults. There is no single test to diagnose ADHD, and many other problems, like sleep disorders, anxiety, depression, and certain types of learning disabilities, can have similar symptoms. If you are concerned about whether a child might have ADHD, the first step is to talk with a healthcare provider to find out if the symptoms fit the diagnosis.

Can probiotics help to prevent constipation?

Over the years, scientists have found strong links between psychiatric disorders and an increased risk of constipation, particularly in older adults. The gut is considered as our second brain. It has more neurons than the spinal cord, and it operates with a similar suite of neurotransmitters as the brain. People with depression oftentimes have lower levels of serotonin, a neurotransmitter in their brain. Neurons in the gastrointestinal (GI) system use serotonin.

In general, the normal range in males is about 270-1070 ng/dL with an average level of 679 ng/dL. A normal male testosterone level peaks at about age 20, and then it slowly declines.

Fish eggs or roes come in a variety of sizes, shapes and colors. It can be obtained from all different kinds of fish, most notably the beluga, other types of sturgeons, salmon and carp. Each type of roe has distinct flavors and uses, though there are also many similarities between them.

What is the link between menopause and chronic fatigue syndrome, and how can I treat it?

Menopause, also known as the change of life, is when a woman’s periods stop. When a woman has not had a period for 12 months, she is considered to have been through menopause. Menopause is diagnosed primarily by its symptoms and usually occurs between the ages of 45 and 55, with an average age of 51. As estrogen production declines, women often develop irregular periods, hot flashes, night sweats, mood swings and fatigue. These symptoms usually develop three to five years before a woman's last period — a time referred to as perimenopause.

Why is getting 8 hours of sleep considered quality sleep?

To sustain life, no more than 3 to 5 hours a night of sleep are required; however, this amount of sleep leads to daytime sleepiness, impaired performance, and reduced executive functions, which are important in decision-making and affect one’s ability to perform complex tasks. To sustain optimal alertness throughout the day, the requirement varies across individuals. For some persons, 5 hours is enough, for others, 10 hours. The mean is 7 to 8 hours for adults.
