Diagnosing drowsiness and its cause may be delayed or missed because the drowsiness may not be severe or consistent enough for a person to seek medical care. In addition, some people may believe that drowsiness is a normal part of aging. Drowsiness is a symptom of many different conditions, and some of them are potentially serious. A thorough medical evaluation is needed to ensure an accurate diagnosis of the reason for the drowsiness.
Mild worm infections undiagnosed in children: Human worm infestations, esp. threadworm, can be overlooked in some cases, because it may cause only mild or even absent symptoms. Although the most common symptoms are anal itch (or vaginal itch), which are obvious in severe cases, milder conditions may fail to be noticed in children. In particular, it may interfere with the child's good night's sleep. Threadworm is a condition to consider in children with symptoms such as bedwetting (enuresis), difficulty sleeping, irritability, or other sleeping symptoms. Visual inspection of the region can often see the threadworms, at night when they are active, but they can also be missed this way, and multiple inspections can be warranted if worms are suspected. See the introduction to threadworm.
Cluster of diseases with difficult diagnosis issues: There is a well-known list of medical conditions that are all somewhat difficult to diagnose, and all can present in a variety of different severities. Diseases in this group include multiple sclerosis, lupus, Lyme disease, fibromyalgia, thyroid disorders (hypothyroidism or hyperthyroidism), chronic fatigue syndrome, diabetes - all of these can have vague symptoms in their early presentations. Also, depression can have some symptoms similar to these conditions, and also the reverse, that many of these conditions can mimic depression and be misdiagnosed as depression.
RLS sleep disorder causing night-time leg sensations often misdiagnosed: A common but relatively unknown sleep-related disorder called Restless Leg Syndrome (RLS) is often misdiagnosed. The typical symptoms are night-time tingling, crawling, or burning sensations in the legs, with the irresistable urge to move the legs. This need for leg movement leads to tossing and turning, or getting up out of bed, all of which interferes with the ability to fall asleep. The sufferer then has the typical symptoms of sleep deprivation during the day: fatigue, tiredness, morning headaches, irritability, poor concentration and so on. This condition is sometimes misdiagnosed as other conditions such as ADHD, sleep disorders, other causes of insomnia, or other causes of leg tingling. Many patients also suffer from a related disorder called Periodic limb movement disorder (PLMD), which causes leg spasms or other jerky movements. See introduction to RLS or introduction to PLMD.
Pituitary conditions often undiagnosed cause of symptoms: There are a variety of symptoms that can be caused by a pituitary disorder (see symptoms of pituitary disorders). For example, fatigue, headache, weight gain, diabetes-like symptoms, and various other symptoms. Pituitary tumors and other similar conditions are not as rare as physicians tend to believe. See introduction to pituitary conditions.
