Neurological consequences

The possible physical long-term consequences of a neurological disorder are different for everyone. Every brain injury is different. Many brain injured people have no visible consequences, but do have invisible consequences. On this page we discus the neurological consequences of brain injury.


Neurological consequences

  • Decline in consciousness and coma
  • Epilepsy
  • Paralysis and loss of strength
    • Hemiplegia: paralysis of one side of the body.
    • Hemiparesis: partial paralysis or loss of muscle strength on one side of the body.
    • Half-sided sensory disturbances (usually on the paralysis side). It varies per person which feeling is reduced (pain, movement, touch, posture warmth and cold).
  • Cramps in hands, arms or legs also see spasticity
  • Spasticity
  • Coordination disorders; difficulty with balance and coordination of movements, ataxia et
  • Proprioceptional disorders balance
  • Movement disorders; motor slowness, hypermobility, spasms, involuntary movements such as chorea huntington
  • Dizziness
  • Headache, migraine
  • Vegetative complaints; nausea, vomiting, pallor, headache, sweating, heart pounding (related to ...)
  • Dysautonomy / POTS
  • Disturbances in sense of touch (gnostic sensibility) and temperature
  • Other sensory impairment; smell, taste, vision, hearing (suddenly deaf) and overstimulation of the nervous system / sensory stimulation.
  • Swallow disorder (dysphagia)
  • Neglect (reduced perception / attention on affected side of the body)
  • Language, speech and articulation disorders; aphasia, dysarthria, speech apraxia
  • Speech disorders: speech is difficult to understand if the muscles of the mouth are paralyzed or cannot move in a coordinated manner (dysarthria)
  • Language disorders: difficulty in finding words, problems in forming or understanding language (aphasia); use of weird words and sentences; use of long sentences or talking too much; take information literally instead of figuratively
  • Disorders of the function of the bladder and intestines; incontinence or not being able to urinate properly
  • Disorders in sexual functions
  • Sleep disorders and CSAS; Central sleep apnea syndrome (if the brain does not control the lungs sufficiently),
  • Dysautonomy-POTS = Postural Orthostatic
  • Tachycardia Syndrome, in which the heart rate rises extremely within 10 minutes after getting up from chair. People can get upset. Blood pressure and heart rate are no longer properly regulated,
  • Forced crying and compulsive laughter (pseudobulbar effect)
  • Other causes of crying after brain injury


Early physical consequences of brain injury

Each brain injury differs so that the early consequences, immediately after the occurrence of injury, also differ. These consequences can disappear.

  • Decline in consciousness
  • Coma
  • Bleeding and haemorrhage (epidural, subdural, subarachnoid, intracranial)
  • Cerebral edema; Just as with a bruise elsewhere in the body, fluid comes out of the bloodstream here. This fluid can put brain tissue under pressure, the brain pressure (intracranial pressure) can rise. This swelling due to moisture is called brain edema, which must be properly addressed.

  • Abscess in specific situations
  • Failure of physical functions
  • Paralysis (left or right)
  • Loss of power
  • Headache
  • Nausea and vomiting
  • Fever in specific situations


Skull injury

In addition to neurological damage, there may also be skull injury; linear skull fracture (skull burst), impression fracture (locally pressed skull due to sharp violence, with the risk of bone splinters), or a skull base fracture (with the risk of ruptured meninges, which can cause colorless brain fluid to flow from the nose and ears). The base is the bottom of the skull - the skull bottom - that rests on the spine.


  • Anterior skull-base fracture is often accompanied by spectacle hematoma; bruising around the eyes.
  • Middle skull-base fracture is often characterized by blood ejection behind the ear, but also blood and cerebrospinal fluid from the ear. Also characterized by hearing and balance problems and problems with facial muscles. Read more...

    A doctor will always perform a neurological examination in the event of neurological damage.
