  2. Neurogenic shock - Wikipedia

    en.wikipedia.org/wiki/Neurogenic_shock

    In neurogenic shock, the body loses its ability to activate the SNS so that only parasympathetic tone remains. The resulting loss of sympathetic tone, which plays a major role in other forms of shock, is responsible for the unique and atypical features mentioned above. [7] [9]

  3. Reflex syncope - Wikipedia

    en.wikipedia.org/wiki/Reflex_syncope

    Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...

    Seizures and syncope can be difficult to differentiate. Both often present as sudden loss of consciousness and convulsive movements may be present or absent in either. Movements in syncope are typically brief and more irregular than seizures. [20] Akinetic seizures can present with sudden loss of postural tone without associated tonic-clonic ...

  5. Vagal tone - Wikipedia

    en.wikipedia.org/wiki/Vagal_tone

    Vagal tone is frequently used to assess heart function, and is also useful in assessing emotional regulation and other processes that alter, or are altered by, changes in parasympathetic activity. [2] [3] Measurements of vagal tone can be performed by means of either invasive or noninvasive procedures.

  6. Spinal shock - Wikipedia

    en.wikipedia.org/wiki/Spinal_shock

    In spinal cord injuries above T6, neurogenic shock may occur, from the loss of autonomic innervation from the brain. Parasympathetic is preserved but the synergy between sympathetic and parasympathetic system is lost in cervical and high thoracic SCI lesions. Sacral parasympathetic loss may be encountered in lesions below T6 or T7.

  7. Hypovolemic shock - Wikipedia

    en.wikipedia.org/wiki/Hypovolemic_shock

    When resulting from blood loss, trauma is the most common root cause, but severe blood loss can also happen in various body systems without clear traumatic injury. [3] The body in hypovolemic shock prioritizes getting oxygen to the brain and heart, which reduces blood flow to nonvital organs and extremities, causing them to grow cold, look ...

    Complex regional pain syndrome (CRPS Type 1 and Type 2), sometimes referred to by the hyponyms Reflex Sympathetic Dystrophy (RSD) or Reflex Neurovascular Dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
