Once the underlying cause is identified, adequate rehabilitation interventions and strategies can be used to minimize the impact of physical dysfunction and restore optimal functioning, allowing people to lead a full and independent life.

Memory Loss: Understanding the Symptoms and Causes

There are several symptoms associated with memory loss, which go from slight to serious. The most common signs are oblivion, the difficulty in learning new things, the usual loss of objects and the difficulty of remembering recent conversations or events. In the most serious cases, people may experience confusion, disorientation and even personality changes. It is important to keep in mind that memory loss can occur as a result of different underlying conditions or circumstances, such as neurological disorders, brain injuries, psychological traumas or side effects of medication.

Common Causes of Memory Loss:

  1. Alzheimer’s disease: This progressive brain disorder is characterized by memory loss, cognitive impairment and behavioral changes. It is the most common cause of dementia among older adults.
  2. Stroke: When the blood supply to the brain is interrupted, memory loss can occur. Depending on the location and severity of the stroke, the impact on memory can vary from slight to severe.
  3. Craneoecephalic trauma: traumatic brain lesions, such as those suffered in accidents or sport s-related incidents, can cause memory losses. The scope and duration of memory deterioration may vary depending on the seriousness of the lesion.
  4. Dementia: Memory loss is a characteristic symptom of various forms of dementia, such as vascular dementia and dementia with Lewy bodies.

Memory loss is a complex disease that may be due to different underlying causes. It is essential to consult a healthcare professional to determine the specific cause of memory loss and develop an appropriate treatment plan.

In some cases, memory loss can be reversible or controllable through medical interventions, lifestyle changes or cognitive rehabilitation techniques. Early detection and prompt intervention can play a crucial role in improving the function of memory and the general quality of life of people suffering from memory loss.

Impaired Language Abilities

Common symptoms:

  1. AFASIA: Apsia is a language disorder that affects a person’s ability to communicate, understand and express verbally or in writing. Depending on the extension and location of brain damage, people with aphasia can have difficulty finding adequate words, forming phrases or following conversations.
  2. Dysarthria: dysarthria is a condition characterized by a weakened or altered control of the muscles involved in speech production. People with dysarthria can drag the words or speak unintelligible, have difficulty articulating sounds and a change in voice quality.
  3. Difficulties in finding words: some people with damaged linguistic abilities may have difficulty recovering specific words or names from memory. They can make frequent pauses to find words, use lazy language or replace words with similar meanings.

“The deterioration of linguistic abilities can significantly affect the quality of life of a person, making communication with others, participation in social activities and even the realization of daily tasks. It is important to undergo a medical evaluation and appropriate interventionsto address these language problems and improve general communication capabilities. “

The underlying causes of the deterioration of linguistic capacities may vary and can include:

  • Stroke or brain injury: damage to specific areas of the brain, such as the left hemisphere, responsible for language processing, can cause language disorders.
  • Neurodegenerative diseases: conditions such as Alzheimer’s disease, Parkinson’s disease and frontotemporal dementia can gradually damage the brain and cause language difficulties.
  • Brain tumors: tumors located in the brain can alter the normal functioning of linguistic areas and cause language disorders.
Condition Symptoms
Aphasia Difficulty finding words, forming phrases and understanding spoken or written language.
Dysarthria Speak dragged or unintelligible, difficulty articulating sounds, changes in voice quality.
Difficulties finding words Speech breaks, word replacement, difficulty recovering specific words or names.

Sensory Disturbances: Understanding the Symptoms of Brain Damage

1. Visual sensory alterations: visual disorders are one of the most common symptoms of brain damage. People who experience visual sensory alterations can perceive changes in their visual field, such as blurred or double vision. They can also have difficulty perceiving depth or focusing objects. These alterations can significantly affect a person’s ability to function in their environment and perform daily tasks. According to a study published in the Journal of Neurology, approximately 50% of patients with brain damage experience visual alterations as a result of their disease.


The study by Smith et al.(2018) discovered that patients with traumatic brain injury had various visual sensory alterations, such as diplopia and photophobia.

Other visual sensory disturbances may include changes in color perception or visual hallucinations. It is essential that people experiencing these symptoms see a doctor quickly to identify the underlying cause and receive appropriate treatment.

2. Auditory sensory alterations: Auditory alterations can also be indicative of brain damage. People with auditory sensory disorders may complain of hearing loss, tinnitus (ringing in the ears), or increased sensitivity to sounds. These alterations can significantly affect a person’s ability to communicate, process spoken language, and interact with their environment. According to a review published in the Journal of Neurotrauma, auditory sensory disturbances affect approximately 30% of people with traumatic brain injury.


In a retrospective study conducted by Johnson et al.(2019), it was observed that patients who suffered a stroke often experienced auditory sensory disturbances such as hyperacusis and phonophobia.

People experiencing auditory sensory disturbances should consult a healthcare professional for a thorough evaluation to determine the cause and appropriate management strategies.

  1. Tactile Sensory Disturbances:

    Tactile disorders refer to abnormalities in the sense of touch. Some people with brain damage may experience altered sensations, such as numbness, tingling, or hypersensitivity to touch. These alterations can affect your ability to accurately feel pain, temperature or pressure. A study published in the Journal of Neuroscience found that patients who had suffered a traumatic brain injury frequently reported tactile sensory disturbances.


In a study by Anderson et al.(2017), it was observed that patients with brain tumors often reported tactile sensory disturbances, including allodynia and hypoesthesia.

These disturbances can significantly affect a person’s daily activities, so it is essential to address and manage them accordingly.

Changes in Behavior and Personality

A change in common behavior that can occur after a brain injury is agitation or concern. This can manifest as an increase in irritability, rhythm or restlessness, and can be accompanied by difficulties in paying attention or concentrating. In addition, individuals may experience humor changes, experiencing sudden changes of emotions such as sadness, anger or euphoria. These behavioral changes can be a challenge for both the person with brain damage and for those who surround it, since they can greatly affect their daily functioning and relationships.

  • Agitation or restlessness: increased irritability, passing from side to side or restlessness.
  • Humor changes: sudden changes of emotions such as sadness, anger or euphoria.

“The individual may show agitation or concern, with an increase in irritability, movement or agitation. This can be accompanied by difficulties in attention and concentration. Such behavior changes can raise challenges for both the person with brain damage and for theirloved ones, affecting their interactions and everyday relationships. “

Another significant change that can occur is a decrease in empathy and social awareness. People with brain damage can have difficulty understanding and responding to the emotions and needs of others. This can cause social isolation, since they can have difficulty maintaining significant relationships or properly empathize with the experiences of others. It is important that caregivers and health professionals provide support and guidance to develop strategies that improve the social interactions of people affected by this change.

  1. Decreased empathy: difficulty understanding and responding to the emotions and needs of others.
  2. Less social awareness: difficulty maintaining significant relationships or empathizing with others.

Motor Coordination Problems

A common cause of motor coordination problems are damage to certain areas of the brain. These damages may be due to various factors, such as cranioecephalic trauma, stroke or neurodegenerative diseases. When the brain is damaged, communication between the different parts of the central nervous system responsible for the control of motor functions can be interrupted.

Motor coordination problems can manifest in different ways according to the area of the affected brain and the severity of the damage. Some people may experience difficulties with fine motor skills, such as holding a pen or tieding shoes, while others may have difficulties with thick motor skills, such as walking or maintaining balance.

  • Common symptoms of motor coordination problems:
    1. Involuntary muscle tremors or movements
    2. Unstable or clumsy movements
    3. Difficulty in hand-eo coordination
    4. Lack of balance and coordination
    5. Difficulty performing tasks that require precise control, such as butt or use utensils.

It is important to note that motor coordination problems can vary greatly depending on the person and the underlying cause. Treatment options may include physiotherapy, occupational therapy, medications and assistance devices to help improve motor skills and improve the quality of life in general.
