When it comes to brain injuries, identifying and understanding the symptoms is crucial for proper diagnosis and treatment. Brain lesions are abnormal areas of tissue, whether a tumor or injury, that can disrupt the normal functioning of the brain. These lesions can range from benign to malignant and can occur in any part of the brain.
1. Cognitive symptoms: Brain injuries can cause various cognitive symptoms, such as difficulty concentrating, memory problems, confusion, and changes in reasoning ability. Patients may experience problems completing tasks that were not challenging before. Additionally, people with brain injuries may have slow thinking or difficulty understanding new information.
Fact: Cognitive symptoms resulting from brain injuries can greatly impact a person’s daily life and ability to perform tasks.
2. Motor symptoms: Brain injuries can also affect a person’s motor abilities. Some common motor symptoms include muscle weakness, lack of coordination, tremors, or even partial or complete paralysis of certain parts of the body. Patients may have difficulty performing simple movements or experience uncontrolled movements.
Tip: Early recognition of motor symptoms associated with brain injuries is vital, as it can help with rapid diagnosis and timely intervention.
3. 3. Sensory symptoms: Brain injuries can alter sensory functions. This may manifest as changes in vision, hearing, taste, touch, or smell.

Understanding Brain Lesions: Definition and Types
Definition of brain injury:
A brain injury is an area of abnormal or damaged tissue in the brain. It can occur in any part of the brain and can affect specific regions or affect multiple areas. Brain lesions can be classified as focal or diffuse. Focal lesions are located in a specific area, while diffuse lesions are more widespread and affect broader regions of the brain.
Types of brain injuries:
- Traumatic injuries: These injuries are caused by head trauma. Traumatic brain injuries can range from mild concussions to severe bruises or bleeding, depending on the extent of the injury.
- Infectious lesions: These lesions are the result of infections that affect the brain, such as bacterial or viral meningitis, encephalitis or brain abscesses. Infections can damage brain tissue and cause lesions to form.
- Inflammatory lesions: Inflammatory brain lesions are caused by autoimmune disorders such as multiple sclerosis or conditions such as vasculitis. These lesions occur because the body’s immune response attacks healthy brain tissue.
In addition to these types, brain lesions can also be classified based on their growth pattern (e. g., benign or malignant tumors) or their vascular origin (e. g., ischemic or hemorrhagic strokes). The specific symptoms and treatment options for brain injuries depend on their type, location, and underlying cause, so an accurate diagnosis and thorough evaluation are essential for effective treatment.
Common Physical Symptoms of Brain Lesions
A common physical symptom associated with brain injuries is headache. Headaches caused by brain injuries can vary in intensity and duration. They can be persistent or intermittent, and people can experience different types of headaches, such as tension headaches or migraines. In some cases, the headache may be localized to the area of the injury, while in others it may radiate to other parts of the head.
It is important to note that not all headaches are indicative of brain injuries, as headaches can have a variety of causes. It is necessary to consult a medical professional to obtain an accurate diagnosis.
Another physical symptom that people with brain injuries may present is dizziness or vertigo. This sensation of spinning or losing balance can occur spontaneously or be triggered by certain movements. Dizziness can greatly affect a person’s quality of life, making it difficult to carry out daily activities and potentially increasing the risk of falls and accidents.
- Dizziness or vertigo
- Nausea and vomiting
- Motor coordination difficulties
- Vision changes
- Seizures
In addition to headaches and dizziness, brain injuries can also manifest with nausea and vomiting. These symptoms may be accompanied by a general feeling of discomfort or dizziness. It is important to note that these symptoms may be nonspecific and present in other medical conditions. Therefore, a thorough medical evaluation is necessary to determine the underlying cause.
Motor coordination difficulties are another physical symptom that can be associated with brain lesions. These difficulties can manifest as weakness or numbness in certain parts of the body, clumsiness or difficulty with fine motor skills. The severity of motor coordination difficulties can vary depending on the location and size of the brain injury.
| Common physical symptoms of brain lesions: |
|---|
| Dizziness or vertigo |
| Nausea and vomiting |
| Motor coordination difficulties |
| Vision changes |
| Seizures |
Changes in vision can also be a physical symptom of brain lesions. These changes may include blurred vision, double vision or even loss of vision in one or both eyes. Brain lesions that affect visual routes can interrupt the transmission of visual signals from the eyes to the brain, causing visual alterations.
Seizures are another possible physical symptom of brain lesions. Seizures occur due to abnormal electrical activity in the brain and can manifest as seizures, involuntary movements, loss of consciousness or alteration of sensations. The presence of seizures can provide valuable information about the nature and location of brain injury.
Cognitive and Behavioral Changes Associated with Brain Lesions
A common cognitive change associated with brain lesions is the deterioration of memory and learning ability. Patients may experience difficulties to remember new information, as well as to recover previously learned information. This can significantly affect its daily functioning and its ability to participate in activities that require memory and learning, such as labor tasks and social interactions. In addition, brain injuries can also cause changes in attention and concentration, which makes people difficult to focus on tasks and maintain sustained attention over time.
Important information:
- Brain injuries can cause cognitive and behavioral changes.
- Specific changes vary depending on the location, size and severity of the lesion.
- The deterioration of memory and learning is a common cognitive change.
- Brain injuries can also affect attention and concentration.
Behavioral changes are another important consequence of brain injuries. These changes can manifest in various ways, such as alterations of personality traits, emotional stability and impulse control. Patients may show sudden changes in humor, greater irritability or difficulty in regulating their emotions. They may also have impulsive behaviors or show lack of inhibition, which can cause social, personal and professional difficulties. In addition, brain injuries can alter the ability to understand and interpret social signals, which hinders social interactions and communication.
Understanding and identifying the cognitive and behavioral changes associated with brain lesions requires an exhaustive evaluation carried out by health professionals. This usually implies a combination of neurological exams, neuroimaging techniques and neuropsychological evaluations. Through the evaluation of these changes, health professionals can develop individualized treatment plans aimed at supporting cognitive functioning, managing behavior problems and improving the general quality of life of people with brain injuries.
Language and Speech Difficulties Caused by Brain Lesions
In people with brain injuries, language and speech difficulties can manifest in different ways based on the location and scope of the injury. The brain regions responsible for language processing include the left hemisphere, particularly the frontal, temporal and parietal lobes. When these areas are affected by an injury, a series of language and speech alterations can occur.
Cerebral lesions that affect the left hemisphere usually cause aphasia, a language disorder characterized by difficulties in understanding and producing spoken and written language. People with aphasia may have difficulty finding adequate words, forming coherent phrases or understanding the speech of others. In addition, they can have difficulty reading and writing.
- Difficulties in finding words (anomia): A common symptom of language alterations caused by brain lesions is the difficulty in finding and recovering words. People can know what they mean, but they find it hard to find the right words or can replace them with incorrect alternatives.
- Speech articulation problems (dysarthria): Brain injuries that affect motor control areas can cause dysarthria, which is characterized by difficulties controlling the muscles used for speech production. This can lead to pronunciation problems, imprecise articulation, or changes in speech rhythm and intonation.
- Reading and writing difficulties: Language and speech difficulties caused by brain injuries can also affect reading and writing abilities. People may have reading comprehension difficulties, spelling and grammar problems, or difficulties forming coherent written sentences.
In general, brain injuries can have a profound impact on speech and language abilities. Understanding the specific symptoms and impairments associated with these injuries can aid in the diagnosis and development of specific intervention strategies to help individuals regain and improve their communication abilities.
Visual Disturbances as a Result of Brain Lesions
1. Visual field deficits: A common visual disturbance caused by brain injuries is the loss of vision in specific areas of the visual field. This can manifest as blind spots, tunnel vision, or loss of peripheral vision. The severity of the visual field deficit depends on the size and location of the brain lesion. For example, lesions to the occipital lobe can cause visual field deficits in specific quadrants, while lesions to the optic nerve can cause complete blindness in one eye.
Types of visual field deficit Characteristics Hemianopia Loss of half the visual field in one or both eyes Quadrantanopia Loss of a quarter of the visual field Scotoma Small blind spot in the visual field
2. Visual hallucinations: Brain injuries can also cause visual hallucinations, in which individuals perceive objects or patterns that are not actually present. These hallucinations can range from simple geometric shapes to complex and vivid scenes. Visual hallucinations are most frequently associated with lesions in the occipital and temporal lobes, as well as the brain stem. It is important to note that visual hallucinations resulting from brain injuries are different from hallucinations caused by psychiatric disorders, such as schizophrenia.
3. diplopia: diplopia, or double vision, is another visual alteration that can occur as a result of brain injuries. This condition makes a person perceive two overlapping images of the same object. The brain lesions that affect the nerves and muscles that control the eye movements can cause the misalignment of the eyes, giving rise to the diplopia. Depending on the location of the lesion, diplopia can occur in one or both eyes and can be temporary or persistent.
Emotional and Mood Disorders Linked to Brain Lesions
Brain injuries can affect several aspects of the mental and emotional wel l-being of an individual, causing the development of emotional disorders and mood. These disorders can significantly affect the quality of life of a person and require timely medical intervention for their effective treatment.
Research has demonstrated a clear association between brain injuries and emotional disorders and mood. When specific areas of the brain are damaged to regulate emotions, symptoms such as depression, anxiety, irritability and emotional instability may appear. In addition, the severity and manifestation of these disorders can vary depending on the location and size of the brain injury.
A remarkable example of emotional disorder associated with a brain injury is the depression after a stroke. This disorder usually occurs in people who have suffered a stroke, especially when the lesion affects regions involved in the regulation of mood, such as the frontal lobe. Post-ictus depression can significantly affect the progress of a person’s rehabilitation and hinder their ability to recover functional independence.
Important note: brain injuries should not be neglected or discarded when emotional or mood disorders appear. Finding medical care and adequate evaluation by a healthcare professional is crucial for a precise diagnosis and appropriate treatment.
Understanding the relationship between brain injuries and emotional and mood disorders is essential for health professionals to develop specific treatment plans. Although medication and therapy can be effective for some people, others may need additional interventions such as rehabilitation, psychoeducation or support of multidisciplinary equipment to address the complex nature of these conditions.
Additionally, advances in neuroimaging techniques, such as magnetic resonance imaging (MRI), have contributed significantly to our understanding of the impact of brain lesions on emotional and mood regulation. These tools help healthcare professionals accurately visualize and localize brain lesions, contributing to the identification of possible risk factors for emotional and mood disorders.
Important note: Early detection and intervention of emotional and mood disorders associated with brain injuries can improve patient outcomes and increase overall well-being. Regular follow-ups and close monitoring of symptoms are vital for optimal care.
