Things to remember
Huntington’s disease is a severely debilitating inherited condition in which selective brain cell death results in a gradual loss of cognitive (thinking), physical and emotional function. Common complications include problems with eating and swallowing (dysphagia), particularly as the disease progresses. The loss of muscle control and coordination means that spilling food from the mouth and choking are possible. Other associated symptoms, such as dementia, may prevent the person from choosing appropriate foods or eating at a manageable speed. Weight loss is often associated with Huntington’s disease, but it doesn’t appear to be a direct result of diet. Some researchers think that weight loss may be linked to other biochemical changes in the body caused by Huntington’s disease. It is strongly recommended that a person with Huntington’s disease and their carers seek professional advice to make sure their diet is nutritious, with lots of calories and easy to eat.
Eating and swallowing problems associated with Huntington’s disease
A person with Huntington’s disease is more likely to choke. Some of the eating and swallowing problems they may experience include:
Enormous increase in appetite
Trying to eat quickly to satisfy urgent hunger
Loss of fine motor control in the face and neck that prevents efficient chewing and swallowing
Inability to close the lips together properly, allowing food to spill out of the mouth
Irregular diaphragm spasm, increasing the risk of inhaling rather than swallowing food
Swallowing too soon, which is a choking hazard
Fear of embarrassment, choking or making a mess – this can make muscular jerking (chorea) worse, which in turn makes eating more difficult
Other complications of the disease, such as changes to thinking ability – these may prompt the person to choose inappropriate foods or try to cram too much food in the mouth at one time.
Food serves many purposes
Food is more than just fuel for our bodies – it is a meaningful social and cultural event. It is important that the person with Huntington’s disease is able to select, prepare and eat their choice of food whenever possible. For example, if they can no longer peel vegetables, perhaps they can wash them.
Food suggestions for those with Huntington’s disease
Always seek the advice of a dietitian who understands the challenges faced by those with Huntington’s disease. General suggestions on food choices include:
Choose frequent small meals instead of three main meals spaced widely apart.
Always have second serves.
Choose soft, easy-to-chew and easy-to-swallow foods (aim for the consistency of porridge).
Use plenty of sauces and gravies to help make main meals easier to manage.
Add plenty of custards, ice-cream and cream to desserts.
Avoid hard foods such as nuts and lollies.
Avoid foods that separate into ‘strings’ or sections while being chewed, such as bacon or tomatoes.
Try to choose foods high in nutritional and calorific value. For example, have a protein-supplemented milkshake rather than a cup of black tea, and eat iced cake instead of water crackers.
Avoid non-fat or low-fat products – always choose full-fat varieties.
Drink fortified beverages such as protein milkshakes or nutritional supplement drinks.
Before the meal
Distractions can make eating very difficult for the person with Huntington’s disease. Suggestions include:
It may be helpful if the person rests for one or two hours before mealtime.
Create a calm and relaxed eating environment. Turn off the television and radio.
Remember that anxiety makes chorea worse, so try to keep the mood light and cheerful.
The person should sit in an accessible spot at the table, just in case choking occurs and a carer has to quickly come to their aid.
Put all eating aids within easy reach.
During the meal
Suggestions include:
The person with Huntington’s disease should be sitting upright while eating, never in a reclining position.
To reduce the risk of choking, the person should angle their head down towards the plate.
Use non-slip table mats.
Use lightweight utensils such as plastic knives and forks.
Utensils with thick handles are easier to hold. Regular cutlery can be converted by slipping the handles into appropriate lengths of foam rubber tubing.
You may like to consider strapping the utensils to the hands.
Use eating aids, such as plate guards, to prevent food being spilled onto the table.
A double-handled drinking cup with spout can make drinking more manageable. Alternatively, use a drinking straw secured into a plastic cup.
A person with Huntington’s disease typically takes a long time to eat. It may help to reheat their meal at regular intervals.
A plastic apron can protect clothes from food spillage.
The person should never try to drink while they have a mouthful of food – the contrasting texture can be confusing and prompt choking.
The person should never be rushed. Allow up to one hour per mealtime.
The person should remain sitting upright for about half an hour following a meal. Lying down too soon after eating increases the risk of reflux and possible choking.
People with Huntington’s disease being fed by others
As the disease progresses, the person may be increasingly unable to manage at mealtime and may have to be fed by their carer. Suggestions for the carer include:
Be sensitive to their feelings. The fact they can no longer feed themselves can cause a wide range of emotions including despair, embarrassment and stress.
Sit opposite the person you are feeding.
Make sure you appear to have all the time in the world – the person with Huntington’s disease may feel anxious and tense if you seem in a hurry.
Suggest they breathe out before taking a forkful. Remind them to stop breathing when it comes time to swallow.
A gentle massage of the face and throat may help the person to swallow.
Give them as much control as possible during mealtimes. For example, they may be able to hold their own drinking cup if you guide it to their mouth.
Tube feeding for a person with Huntington’s disease
A person in the later stages of Huntington’s disease may be unable to chew and swallow safely or effectively, and tube feeding may be suggested as an option. Generally, the type of tube used is a percutaneous endoscopic gastroscopy tube (PEG tube), commonly referred to as PEG feeding. Insertion of a PEG tube usually involves a day procedure in a hospital. PEG feeding may not solve all the problems faced at this stage and the decision to tube feed is an emotional one. It needs to be sensitively discussed beforehand with healthcare professionals.
