It is 4 years old. I started it from seed. It has grown in height is about 2 ft. tall, when it gets a few leaves on top they turn black and fall off. The palm still grows and has always been in a pot and indoors. I re-potted it in spring and used new cactus soil.
thanks for your answer
I would guess that the soil is staying too wet. You may be watering when the surface feels dry, but the soil under the surface, down near the bottom of the pot, may still be damp. Use an electronic moisture meter, or test with a bamboo kebob skewer - when you pull it up it should feel dry. Don't water until the soil feels dry. You have made a good start by using cactus soil; next time you repot, add perlite to it, in a ratio of 1:1. And always remember, this plant is not a palm of any kind. It's more of a cactus. https://www.gardeningknowhow.com/houseplants/madagascar-palm/madagascar-palm-care.htm
My Madagascar Palm's trunk has turned a greenish yellow. What does this mean?
This could be watering issues, to much water or even to little.
Also if the plant is started to go dormant you may see a color change.
As long as the trunk is not soft, I would not worry to much.

Several months ago my pachypodium (sold under the name geayi) started to drop its leaves. At first just sparsely at the bottom of the plant, but increased in frequency. I thought it may be root rot so I left it out in the sun for a while and that made the leaves worse and the top of the plant looks as though it caved in and the spines and leaves around that portion of the plant died. What can I do to save my pachypodium?
It looks like your plant may not be getting enough water, or a combination of not enough water and sunlight that could be too bright, too direct. As long as the pot is well-drained, you should be able to water your palm whenever the surface soil is dry.
Make sure the plant is in bright but not direct sunlight, try spritzing it lightly in the early morning or late evening and water it when the surface soil is dry. Re-pot it if the container isn't draining well.

I have about 8 year Madagascar Palm. Why is my Madagascar leaf becoming black? I did not change the location of the plant and wait until about 1 cm of the soil is dry and then I water. I live in Madagascar.
Madagascar palm, or Pachypodium lamerei, is quite sensitive to overwatering since it is a succulent. Underwatering can also cause brown leaf tips, but this is unlikely to be the problem, since you are clearly giving it enough water. You may need to reduce watering even more, making sure the top 6 cm or so are dry before watering.
Other possibilities for brown leaf tips include excessive salt or fertilizer in the soil, among other problems discussed here:

Why are the leaves turning yellow and falling off?
The most likely reason is overwatering or poor drainage in its container. Since Madagascar palm is a succulent, it needs less water than other plants and should be kept in a potting soil designed for cacti and succulents.
Excessively high pH in the soil can also cause yellowing leaves.
Our Madagascar palm broke off at the base after our really wet winter here in California. Can it be saved some how?
You can attempt to propagate a section of the trunk.

What's best?
Cactus potting mix is best to use.
