According to the World Health Organization, neurological disorders affect millions of people worldwide, and the prevalence increases with age [1].
As the world’s population ages, it is crucial to recognize the warning signs of certain conditions to detect and treat them as early as possible.
Detecting neurological disorders in their initial stages can significantly affect treatment outcomes.
Early diagnosis allows for prompt initiation of appropriate therapies, potentially slowing down the progression of the disease or even reversing some of the symptoms.
This article will delve into the 7 warning signs of neurological disorders in adults, exploring the different symptoms, their potential causes, and the importance of consulting a healthcare professional for further evaluation.
7 early signs of adult neurological problems
1. Sudden onset of severe headaches
Severe headaches are intense pain, often described as throbbing, stabbing, or pulsating. They can be debilitating and significantly impact a person’s daily functioning.
If you experience sudden headaches without any apparent cause, it may be a symptom of a neurological condition.
Some of the potential causes of sudden severe headaches include:
- Migraines
- Cluster headaches
- Tension headaches
- Subarachnoid hemorrhage
- Brain tumor
- Meningitis
How to differentiate a migraine from a neurological disorder
While migraines can be excruciating and disruptive, they typically do not indicate an underlying neurological disorder.
In case you suddenly have severe headaches without any history of migraines, it is advisable to seek the opinion of a healthcare professional for further assessment.
This is particularly important if the headache is accompanied by additional symptoms, like fever, neck stiffness, confusion, or loss of consciousness, as these could signal a more serious neurological issue [2].
2. Unexplained memory loss
Memory loss can manifest in various ways, affecting short-term and long-term memory. Short-term memory loss involves difficulty recalling recent events or information, while long-term memory loss affects the ability to remember past experiences and learned knowledge.
Unexplained memory loss, particularly when it impacts daily functioning and occurs alongside other symptoms, can be a warning sign of a neurological-related disability.
Memory loss can result from several factors, including normal aging, stress, sleep deprivation, and certain medications.
However, memory loss may indicate an underlying neurological issue when severe, progressive, or unexplained. Some potential neurological causes of memory loss include [3]:
- Alzheimer’s disease
- Vascular dementia
- Parkinson’s disease
- Traumatic brain injury
- Brain tumors
What’s the difference between normal aging and a neurological disorder
Please remember that experiencing some memory decline is a natural aging process.
However, significant memory loss that impacts daily functioning occurs suddenly or is accompanied by other symptoms warrants further investigation by a healthcare professional.
Early detection and intervention can improve outcomes for individuals experiencing memory loss due to a neurological disorder.
3. Unusual muscle weakness
Muscle weakness is reduced ability to generate force or perform physical tasks. It can appear in various ways, such as trouble lifting things, going upstairs, or holding onto something tightly [4].
Unusual muscle weakness that cannot be attributed to physical exertion, lack of sleep, or other identifiable factors could be a symptom of a neurological condition.
Various factors can contribute to muscle weakness, including overexertion, aging, injury, and certain medical conditions.
However, unexplained, persistent, or progressive muscle weakness may indicate an underlying neurological issue. Some potential neurological causes of muscle weakness include:
- Multiple sclerosis (MS)
- Amyotrophic lateral sclerosis (ALS)
- Guillain-Barré syndrome
- Myasthenia gravis
- Spinal muscular atrophy
How does muscle weakness relates to neurological disorders
Many neurological disorders can cause muscle weakness, damaging the nerves that send signals to the muscles. Therefore, muscle weakness can be a primary symptom of these conditions.
Early recognition of unusual muscle weakness and consultation with a healthcare professional can help identify the underlying cause and initiate appropriate treatment, improving the prognosis for individuals with neurological disorders.
4. Loss of balance and coordination
Balance and coordination issues can manifest in various ways, like instability while standing or walking, difficulty performing fine motor tasks, or frequent falls [5].
These issues can significantly impact a person’s ability to perform daily activities and may signal an underlying neurological issue.
Several factors can contribute to balance and coordination issues, including inner ear problems, muscle weakness, joint issues, or certain medications.
However, these problems may indicate a persistent, unexplained, or severe neurological condition. Some potential neurological causes of balance and coordination problems include:
- Parkinson’s disease
- Cerebellar ataxia
- Multiple sclerosis (MS)
- Brain tumors
- Stroke
How do neurological issues affect balance and coordination?
Many neurological disorders affect the brain regions and nerves responsible for controlling balance and coordination, leading to difficulties in these areas.
Identifying and addressing balance and coordination issues early on can help improve treatment outcomes and maintain independence for individuals with neurological disorders.
Consulting a healthcare professional for further evaluation is essential when experiencing unexplained or persistent balance and coordination problems.
5. Numbness or tingling sensations
Often described as “pins and needles” or a feeling of “falling asleep,” numbness or tingling sensations can occur for various reasons.
These abnormal sensations can affect any body part but are commonly experienced in the hands, feet, arms, or legs.
They may signal a neurological issue when they occur frequently, persistently, or without apparent cause.
Numbness and tingling sensations can result from several factors, including pressure on a nerve, poor blood circulation, or injury.
However, when these sensations are unexplained, severe, or widespread, they may indicate an underlying neurological disorder [6].
Some potential neurological causes include:
- Peripheral neuropathy
- Carpal tunnel syndrome
- Multiple sclerosis (MS)
- Cervical spondylosis
- Guillain-Barré syndrome
Can numbness and tingling be signs of a serious problem?
Numbness and tingling sensations can be primary symptoms of various neurological disorders, as these conditions often damage the nerves responsible for transmitting sensory information.
Recognizing and addressing these abnormal sensations early on can help identify the underlying cause and initiate appropriate treatment, improving the prognosis for individuals with neurological disorders.
Consult your medical professional immediately when experiencing unexplained or persistent numbness and tingling sensations.
6. Persistent vision problems
Vision problems can manifest in several ways, such as blurred or double vision, loss of visual field, difficulty recognizing colors, or sudden vision loss.
While many vision issues can be attributed to refractive errors, aging, or eye diseases, persistent or unexplained vision problems may indicate an underlying neurological disorder.
Various factors can contribute to vision problems, including eye strain, cataracts, glaucoma, or macular degeneration.
However, when vision problems are persistent, sudden, or unexplained, they may signal a neurological issue. Some potential neurological causes include [7]:
- Optic neuritis
- Parkinson’s
- Stroke
- Migraines
- Temporal arteritis
- Alzheimer’s
What to do with persistent eye problems
It is essential to consult a healthcare professional for further evaluation if you experience persistent or unexplained vision problems, especially if accompanied by other symptoms such as headache, pain, or neurological deficits.
Early detection and intervention can improve outcomes for individuals experiencing vision problems due to a neurological disorder and, in some cases, prevent permanent vision loss.
7. Sudden or gradual speech difficulties
Speech difficulties can manifest in various ways, such as slurred speech, stuttering, difficulty finding the right words, or problems with voice quality.
These issues can impact a person’s communication ability and signal an underlying neurological disorder.
Several factors can contribute to speech difficulties, including stress, anxiety, hearing loss, or certain medications.
However, persistent, unexplained, or sudden speech difficulties may indicate a neurological issue. Some potential neurological causes of speech difficulties include:
- Stroke
- Brain tumors
- Parkinson’s disease
- Multiple sclerosis (MS)
- Amyotrophic lateral sclerosis (ALS)
How do speech difficulties relate to neurological disorders
Speech difficulties can be primary symptoms of various neurological disorders, as these conditions often involve damage to the brain regions or nerves responsible for controlling speech and language.
If someone is experiencing speech difficulties due to a neurological disorder, seeking early consultation with a healthcare professional can be helpful.
It can lead to identifying the underlying cause and starting appropriate treatment, improving communication and overall quality of life.
How do you check neurological symptoms?
Diagnostic tests help doctors identify the specific disorder, assess its severity, and monitor its progression over time [8].
These tests can also rule out other potential causes of the symptoms, providing valuable information to guide treatment decisions.
The specific diagnostic tests will depend on the patient’s symptoms, medical history, and the suspected neurological disorder. Some of the most common tests include:
Neurological examination
A comprehensive evaluation of a patient’s mental status, cranial nerve function, motor function, sensory function, reflexes, coordination, and gait. This examination can help identify abnormalities in the nervous system that may indicate a neurological disorder.
Blood tests
These tests can help identify potential underlying causes of neurological symptoms, such as infections, inflammation, metabolic disorders, or vitamin deficiencies. Some blood tests can also help diagnose specific neurological conditions, such as multiple sclerosis or Guillain-Barré syndrome.
Imaging techniques
Medical imaging technologies like MRI, CT, and PET scans can produce comprehensive brain and spinal cord images. These images can help pinpoint structural irregularities, tumors, inflammation, or other underlying neurological conditions that may cause certain symptoms.
Electroencephalogram (EEG)
An EEG records electrical activity in the brain through electrodes placed on the scalp. This test can help diagnose epilepsy, sleep disorders, or encephalopathy.
Electromyography (EMG) and nerve conduction studies
These tests measure the electrical activity of muscles and nerve signal speed to aid in diagnosing conditions like peripheral neuropathy, myasthenia gravis, or ALS.
Lumbar puncture (spinal tap)
A lumbar puncture involves collecting a sample of cerebrospinal fluid (CSF) from the spinal canal. Analyzing the CSF can help diagnose conditions such as meningitis, multiple sclerosis, or subarachnoid hemorrhage.
Genetic testing
These tests can identify specific genetic mutations or abnormalities associated with certain neurological disorders, such as Huntington’s disease, Parkinson’s disease, or certain forms of dementia.
Accurate diagnosis is crucial for determining the appropriate treatment and management plan for individuals with neurological disorders.
In closing
We’ve explored the seven warning signs of neurological disorders in adults. Recognizing these warning signs is crucial for early detection and intervention, which can improve outcomes for individuals with neurological disorders.
We also discussed the importance of diagnostic tests in identifying neurological disorders. Some common diagnostic tests include neurological examinations, blood tests, imaging studies, EEG, EMG, lumbar punctures, and genetic testing.
Healthcare professionals will determine the most appropriate diagnostic tests based on the individual’s symptoms, medical history, and suspected neurological disorder.
Early and accurate diagnosis is essential for initiating appropriate treatment and improving the quality of life for individuals with neurological disorders.
