Issens, also known as Isolated Sensory Symptoms or Sensory Aura without Migraine, is a neurological condition that affects the sensory system.

It is a rare condition that causes various sensory disturbances, such as tingling, numbness, or visual disturbances, without the presence of a headache or migraine. Identifying the symptoms of Issens can be challenging as they can mimic other conditions and vary from person to person. In this article, we will discuss the common symptoms of Issens to help individuals understand and recognize this condition.

1. Visual Disturbances

One of the most common symptoms of Issens is visual disturbances. Patients may experience temporary blind spots, blurry vision, or the appearance of flashing lights or zigzag lines.

These visual disturbances can be extremely disruptive and may affect daily activities such as reading, driving, or watching television.

2. Tingling or Numbness

Tingling or numbness in the body is another symptom of Issens. It may start in one specific area and spread to other parts of the body.

The sensation is often described as a “pins and needles” feeling and can be accompanied by a loss of sensation or a feeling of the limbs being asleep. These sensations can come and go or persist for longer durations.

3. Sensory Sensitivity

Individuals with Issens may also develop sensory sensitivities. They may become hypersensitive to touch, sound, or light. Everyday stimuli that may not bother others can become overwhelming and lead to discomfort or pain.

This sensory overload can make it challenging to engage in daily activities or interact with others.

4. Dizziness or Vertigo

Dizziness or vertigo can also accompany Issens symptoms. Patients may experience a spinning or whirling sensation, loss of balance, or a feeling of being lightheaded.

These symptoms can be debilitating and interfere with a person’s ability to perform tasks that require concentration or physical coordination.

5. Motor Weakness or Difficulty

Motor weakness or difficulty is another symptom that individuals with Issens may experience. They may find it challenging to grip objects, perform fine motor skills, or experience weakness in specific muscles or limbs.

This weakness can be temporary or persistent and may affect daily activities and overall quality of life.

6. Temperature Changes

Unexplained temperature changes can also be a symptom of Issens. Some individuals may experience sudden heat or cold sensations in specific areas of the body.

These temperature changes can be uncomfortable and may lead to discomfort or difficulty regulating body temperature.

7. Altered Sensations

Issens can cause altered sensations in different parts of the body. Patients may report a feeling of pressure, tightness, or a “crawling” sensation.

These sensations can occur randomly and may affect various areas, such as the face, limbs, or torso. These altered sensations can be distressing and interfere with daily activities.

8. Speech and Language Difficulties

In some cases, Issens can affect speech and language abilities. Individuals may experience difficulty finding the right words, slurred speech, or changes in their voice.

These difficulties can impact communication and social interactions, leading to frustration and isolation.

9. Psychological Symptoms

Psychological symptoms can also arise in individuals with Issens. Anxiety, depression, irritability, or mood swings may occur due to the chronic discomfort and disruption caused by the sensory disturbances.

It is essential to address these psychological symptoms and consider appropriate support alongside managing the physical symptoms.

10. Fatigue

Fatigue is a common symptom experienced by Issens patients. The constant sensory disruptions and the challenges they pose can be physically and mentally draining.

The fatigue may not be alleviated by rest and can significantly impact a person’s energy levels and overall well-being.
