What Is Arnold-Chiari Malformation?

Arnold-Chiari malformations, also known as Chiari malformations, are structural defects within the cerebellum and base of the skull. The cerebellum is the area of the brain that controls your balance. Usually, portions of the brain stem and the cerebellum sit above an opening in your skull, and your spinal cord can pass through it.

what is acm

It’s called a Chiari malformation (CM) when your cerebellum extends below this area and into the upper spinal canal. This condition causes pressure on your brainstem and cerebellum. In turn, this blocks the flow of cerebrospinal fluid (CSF) that acts as a cushion for your spinal cord and brain.

CSF also plays a role in removing waste products from your brain and circulating chemical and nutrients that have been filtered from your blood. The condition negatively impacts many of your physical functions. Chiari malformation is uncommon. However, imaging tests are leading to a more frequent diagnosis of the condition that often occurs when a part of your skull is misshapen or abnormally small. Speak to your doctor without delay if you feel you could be affected by the condition.

History of Arnold-Chiari Malformations

Hans Chiari was an Austrian pathologist who initially identified the three types of Chiari malformation in 1981. Julius Arnold went on to further expand the meaning of CM type ll. Some medical sources, therefore, call the condition Arnold-Chiari malformation, although there are a handful of interchangeable names for the condition that are in use. These include Tonsillar Ectopia, CM and Hindbrain Herniation.

Types of Arnold-Chiari Malformations

Today, there are four identified types of Chiari malformations.

  • CM type l develops as your brain and skull grow. Symptoms may not occur until later in childhood or adulthood.
  • CM type ll and type lll are congenital, which means they are present at birth, and doctors can diagnose them.
  • CM type IV is rare.

Type 0 might be part of this list, but it’s a controversial and newly identified type of Chiari malformations. Syrinix (a fluid-filled cavity in the spinal cord) is present, but doesn’t meet other criteria of the condition.

The treatment you receive for Arnold-Chiari malformation depends on the symptoms, form and severity. If you’d prefer to treat your non-surgically related symptoms in a natural way, perhaps medical pot can help.

Chiari Malformation Type l

Severe headaches are a classic symptom of the disorder. These often occur after you’ve strained, coughed or sneezed. You may also experience the following if you have CM type l:

  • Poor hand coordination
  • Neck pain
  • Dizziness
  • Unsteady gait and balance problems
  • Tingling and numbness in your feet and hands
  • Speech problems like hoarseness
  • Difficulty swallowing, at times, accompanied by vomiting, gagging and choking
  • Vision problems, such as double or blurred vision

Other less common symptoms include:

  • Slow heart rhythm
  • Buzzing or ringing in your ears (tinnitus)
  • Abnormal breathing, like central sleep apnea where breathing sometimes stops while you’re asleep
  • Weakness
  • Curvature of the spine (scoliosis) related to spinal cord impairment

Chiari Malformation Type ll

In type ll, a larger amount of tissue extends into your spinal canal than in CM type l. Additionally, the symptoms and signs may relate to a form of spina bifida known as myelomeningocele, which is a condition that almost always is seen alongside CM type ll. In myelomeningocele, your spinal canal and backbone hadn’t correctly closed before you were born. Symptoms include:

  • Weakness in arms
  • Changes in breathing patterns
  • Quick downward eye movements
  • Swallowing problems like gagging

Chiari Malformation Type lll

This is perhaps the most severe type of CM. It’s characterized by a part of the cerebellum — the lower back area of your brain — or your brain stem extending through an abnormal opening in the rear of your skull. This type of CM is either diagnosed via ultrasound during pregnancy or at birth. It may cause neurological problems and has a higher mortality rate.

Chiari Malformation Type lV

In type IV, the cerebellum is either undeveloped or incomplete, which is referred to as cerebellar hypoplasia. In some patients, parts of the spinal cord and skull are exposed and visible. This is the most severe form of Chiari Malformation, and, if it occurs during infancy, it can be fatal.

Symptoms of Arnold-Chiari Malformation

There are many individuals with Chiari malformation who have no symptoms or signs of the condition, and therefore, don’t need treatment. The condition may only be flagged during tests for something that’s entirely unrelated. For others, Chiari malformation can cause various problems, depending on the severity and type you have.

These malformations show up as structural defects within the cerebellum, which is the part of the brain that controls balance. The pressure on the cerebellum can block the flow of cerebrospinal fluid, which usually protects and surrounds the brain and spinal cord. As a result, loss of balance, disorientation, vision problems, lack of coordination and frequent numbness can occur.

The most commonly recognized form of CM is Type I, which can be asymptomatic and is often uncovered incidentally during routine examinations for other conditions. Type II is often accompanied by a form of spina bifida, causing the spinal cord to protrude through an opening in the back. Type III is the most severe form of CM, which causes severe neurological defects.

Effects of Arnold-Chiari Malformation

Suffering from Arnold-Chiari malformation is just that, suffering. The pain and side effects of the condition are isolating and debilitating. It can be tough to gain respite. When you’re constantly in pain, you may feel disconnected even from those closest to you.

Your symptoms may be unpredictable and erratic. You may be unable to make plans for fear or feeling too unwell to function. You probably feel overwhelmed and lonely as you search for answers. Other feelings you might need to deal with include irritability, depression and short-temperedness. For this reason, it’s crucial to get the right treatment such as medical cannabis for Arnold-Chiari malformation that can help you.

Arnold-Chiari Malformation Statistics

  • The prevalence of CM in the general population is around less than one in 1000 according to the American Association of Neurological Surgeons.

Current Treatments Available for Arnold-Chiari Malformation and Their Side Effects

As previously stated, some cases of CM do not present any symptoms, and therefore don’t interfere with your quality of life. Generally, doctors recommend regular MRI scans to monitor your condition if this is the case. If you’re experiencing headaches or pain, you’re prescribed painkilling medications to help ease your symptoms. Some painkillers can be addictive and may have adverse side effects if taken over a protracted period.

As far as treatment is concerned, decompressive surgery can be utilized for more extreme cases, removing the second and third cervical vertebrae. Additionally, the stopping of spinal fluids may be aided by an implanted shunt.

For patients seeking less invasive treatment plan, medical-grade marijuana is recommended for immediate pain relief specifically targeting chronic muscle pain, weakness, headaches and fatigue. Sativa-dominant strains work best to reduce nausea, reduce and relieve pain and increase muscle capability.


Surgery is the only treatment available to many people to halt the progression of central nervous system (CNS) damage and to ease their symptoms. For most people, surgery can stabilize or improve symptoms of CM. More than one surgery may be needed if you go down this route.

  • Posterior Fossa Decompression. Posterior fossa decompression is the commonest surgery to treat Arnold-Chiari malformation. The procedure makes added space for your cerebellum and relieves the pressure on your spinal cord. It should help restore the flow of your cerebrospinal fluid. It relieves symptoms in some but not all cases.
  • Myelomeningocele. Children and infants with myelomeningocele could need surgery to close the opening in their back and to reposition their spinal cord. When this is done prenatally, it places the brainstem and cerebellum into a more normal position and reduces the likelihood of hydrocephalus (water on the brain).
  • Hydrocephalus. A tube called a shunt can be used if you have this condition. The purpose of this is to relieve pressure within your head and to drain away excess fluid.
  • Third Ventriculostomy. Third ventriculostomy is another treatment for hydrocephalus and improves the flow of cerebrospinal fluid from your brain. In cases where surgery doesn’t work, you may have an operation to insert a shunt in your spinal cord, draining away increased fluid in its central canal.
