Online neurology consultations

Headaches can present in many different ways. Neurological causes include tension-type headaches, migraine with or without aura and cluster headaches. Some people also experience nausea, sensitivity to light, visual disturbances or symptoms related to certain movements.

Migraine can be influenced by a combination of genetic, hormonal, neurological and environmental factors. Changes in sleep, certain habits or specific circumstances may coincide with the onset of episodes, although triggers vary from person to person.

Vertigo, a feeling of unsteadiness or sensitivity to movement can occur in a number of conditions. Vestibular migraine is one possibility, although symptoms may also be related to the inner ear or other parts of the nervous system.

When assessing vestibular migraine symptoms, the context and progression of the symptoms are especially important. The doctor will also consider associated features such as tinnitus, visual disturbances or photophobia before advising on the next steps.

Tingling, numbness or a pins-and-needles sensation can occur when a nerve is irritated or compressed, when peripheral nerves are affected, or when another part of the nervous system is involved. These sensations may occur in the hands, feet, legs, arms or face.

The causes of tingling in the hands can vary widely. To help determine what may be contributing, the doctor will consider where the sensation occurs, how long it lasts, whether it affects one or both sides, and whether it is associated with a particular posture, movement or activity. Numbness in the arms and legs can also follow different patterns. If these symptoms persist, recur frequently or are accompanied by weakness, changes in coordination or other symptoms, a medical assessment is recommended.

Pain caused by a nerve disorder may require a specific approach. The most appropriate neuropathic pain treatment depends on the underlying cause, the characteristics of the pain, other health conditions and any medication the patient is taking.

Muscle weakness can affect mobility, coordination or the ability to carry out everyday activities. Some signs may initially seem minor, such as frequently dropping objects, noticing reduced dexterity in the hands or becoming tired more quickly than usual when walking.

Tremors are involuntary movements that can have different characteristics and causes. Essential tremor is common and may occur in several members of the same family, whereas tremor associated with Parkinson’s disease has different features and is often most noticeable at rest. Before considering essential tremor treatment, it is important to assess how the tremor presents, how long it has been present and how much it interferes with daily activities. This information helps distinguish it from other involuntary movements.

The progression and distribution of these symptoms may also be relevant when assessing conditions such as multiple sclerosis, cervical myelopathy or certain peripheral neuropathies. The specialist will decide whether the available information is sufficient for follow-up or whether further tests are needed.

Sleep has a direct effect on attention, memory and day-to-day functioning. Persistent difficulty sleeping, excessive daytime sleepiness or changes in usual sleep patterns may be accompanied by fatigue, poor concentration or a sense of slowed thinking.

Some sleep problems are associated with specific neurological disorders. Restless legs syndrome, certain REM sleep disorders and narcolepsy may require different approaches to assessment depending on the symptoms and how they have developed.

Brain fog also has no single cause. It may occur alongside poor sleep, stress, hormonal changes or other health problems, so it is important to consider when it began and what other symptoms are present.

During the assessment, the doctor may review sleep habits, cognitive changes and relevant medical history. Depending on the situation, they may recommend follow-up, additional tests or an in-person assessment.

Stress and anxiety can be accompanied by physical sensations that may be worrying and can resemble neurological symptoms. These may include dizziness, tremor, tingling or temporary visual disturbances.

These symptoms can occur during periods of emotional strain, after significant changes in personal or working life, or when sleep has been disrupted for a prolonged period. However, a neurological symptom should not automatically be attributed to stress simply because it appears during a difficult period.

For this reason, the assessment considers how the symptoms began, how long they last, how often they occur and whether they are associated with particular situations. Medical history and other signs that may point to a different cause are also taken into account.

A specialist can help make sense of this information and decide whether follow-up is sufficient or whether further assessment is appropriate. If a physical examination, additional tests or in-person care are needed, they will explain this during the consultation.
